From the New York Post (via the Roosevelt Islander blog):
"Blackwell's Island" will be offered May 23 at Christie's. The large-scale oil has never come to auction before.
The 1928 painting has been exhibited in major museums including New York's Museum of Modern Art, The Whitney Museum of American Art and the Museum of Fine Arts in Boston.The piece is called "Blackwell's Island," of course, because Roosevelt Island didn't take its current name until 1971.
The weird thing is, the isle was only called Blackwell's Island until 1921, when it began a 50-year stint as Welfare Island. If Hopper painted this in 1928, he was using an out-of-date name.
I guess it's like old-timers in San Francisco who still refer to Cesar Chavez Street as Army Street. (Or how I still call Netflix "Qwikster.")
