The lot is a 1951 Gertrude Abercrombie still life of nine seashells, it was authenticated by the scholar the auction world treats as the last word on her work, and Freeman’s put it in a New York sale on October 1 with an estimate that runs to $250,000
A treasure hunter reached a Michigan estate sale in July after most of the house had already been picked over, and kept looking anyway. In a hallway leading to the garage hung a slate gray painting of scattered seashells.
The price tag said $30. In the lower left corner, in thin script, sat a name and a year: Abercrombie, ’51. The collector took the gamble and carried the thing home.
That painting is now lot 3 in Freeman’s Post-War and Contemporary Art sale in New York, scheduled for October 1, carrying an estimate of $150,000 to $250,000 on the house’s catalogue listing.

The catalogue page that gave it a name
After the purchase, the new owner detoured on a family vacation to see the Abercrombie retrospective then hanging at the Milwaukee Art Museum, Smithsonian magazine reported. The exhibition catalog was where the guess turned into something else.
Inside it was an archival photograph of that exact painting in its original frame, displayed beside the real seashells it depicts. The image had first run with a review of her 1952 show at the Newman Brown Gallery in Chicago.
The scholar who signed off on it
The owner then took the canvas to Susan Weininger, an art historian at Roosevelt University and the authority auction houses lean on for this artist. She authenticated it, and the painting was consigned to Freeman’s.
Freeman’s had reason to be nearby. The museum’s own announcement lists Freeman’s Auction and Appraisals among the show’s contributing sponsors and sets the run from March 27 to July 19, 2026, according to the Milwaukee Art Museum.
What the lot sheet says now
The catalogue entry describes oil on Masonite in its original frame, 8 by 11 inches, one of 98 lots in the October 1 session. Bidding is set to open at $75,000 against the $150,000 low estimate.
Weeks before the discovery, Zachary Wirsum, the house’s senior vice president for postwar and contemporary art, had told visitors on an exhibition tour that Abercrombie paintings still surface at estate sales. He said in a statement that “one of those ‘once in a while’s would occur less than a month later.”
The multiplication, done slowly
Put the estimate next to the price tag and the scale of it lands properly. Divide $250,000 by $30 and you get 8,333, so the high estimate is more than eight thousand times what the buyer handed over at the door, in our own arithmetic.
The floor is not modest either. The $150,000 low estimate works out to exactly 5,000 times the purchase price, and the $75,000 opening bid on its own is 2,500 times it, by the same calculation.
What the buyer’s premium takes back
An estimate is a hammer figure, and nobody pays only the hammer. Freeman’s conditions of sale, effective April 21, 2026, set the buyer’s premium for live auctions at 28 percent of the hammer price up to and including $1,000,000.
Run that against the numbers on the lot sheet. A $250,000 hammer adds $70,000 in premium, so the winner writes a check for $320,000 before any sales tax, in our calculation, per the published conditions of sale. At the low estimate the premium is $42,000, for $192,000 in all.
An estimate is not a sale
The same document is blunt about what those figures mean. Freeman’s states that estimates cannot be relied on as a prediction or guarantee of the actual selling price, and that they leave out the premium, taxes and other charges.
So until the gavel comes down in New York, the $250,000 is a projection on a catalogue page. Nobody has made that money, the painting has not changed hands, and the only sum anyone has actually paid for it is thirty dollars.
Whose shells these were
Abercrombie painted the picture in 1951 from nine seashells owned by Robert Merriam, alderman of Chicago’s fifth ward from 1947 to 1955. His ward covered Hyde Park, the neighborhood where she lived, worked and held court.
Shells ran through her work for decades, usually single specimens with a hole or a crack in them. Art historians had long assumed she invented that damage. One of Merriam’s nautilus shells turned out to carry both a hole and a crack.
How a Chicago painting reached a Michigan hallway
The work was shown in Chicago, New York and Milwaukee across 1952 and 1953, priced between $50 and $150. Abercrombie later gave it to John Reynolds, a doctor in Kalamazoo, Michigan, in exchange for a medical procedure.
It stayed with the Reynolds family for 75 years, which is why a Chicago painting surfaced at a Michigan estate sale. Julian Baumgartner, who runs a fine art restoration studio in Chicago, cleaned it ahead of the auction and filmed the work.
What $250,000 looks like from Brazil
Converted at the Banco Central do Brasil closing rate of R$ 5.1575 to the dollar on September 18, 2026, the high estimate comes to roughly R$ 1.29 million. The $30 the collector paid was about R$ 155 at that same rate.
Add the buyer’s premium and the gap widens again. The $320,000 a winning bidder would owe on a top-estimate hammer is close to R$ 1.65 million, which is real-money territory in a market where a Tarsila do Amaral canvas set the national auction record at R$ 57.5 million in 2020.
The Brazilian version of the same story
Brazil runs the same machinery for lost pictures, and it is busy. Roughly 200 Candido Portinari paintings are recorded as missing, and in December 2024 the Correios issued a stamp series showing four of them, including Lampiao e Maria Bonita, so that someone might recognize one on a wall.
The authentication step works much as it did for the shells. The Projeto Portinari, founded in 1979, has catalogued more than 5,300 works, and its expert commission issues a single certificate printed by the Casa da Moeda, as the project describes its own process.
Where the Abercrombie market stands
The rediscovery lands in a market that has moved fast. Message for Mercy, a 1950 canvas, sold for $1.02 million at Sotheby’s in New York on November 21, 2025, the first Abercrombie to clear seven figures at auction.
It beat a record of $864,100 set by Silo at Aledo at Bonhams thirteen months earlier. Sotheby’s credited research by Susan Weininger on that lot too, the same scholar whose word turned a $30 hallway find into lot 3 on October 1.
