It was one of two paintings Beth Feeback bought from a Goodwill store in North Carolina with the intention to paint over them. She spent $20. What would have been a pet portrait will likely become a chunk of extra cash when the painting is offered at auction in September. Valued at between $15,000 and $20,000, the large striped canvas is the work of Ilya Bolotowsky. According to ABC News, the previous owners took the painting to Goodwill because it was too big for their basement. Born in Russia, Bolotowsky immigrated to New York in 1923. He attended the National Academy of Design and became associated with a group called “The Ten Whitney Dissenters,” or simply “The Ten,” artists, including Louis Schanker, Adolph Gottlieb, Mark Rothko and Joseph Solman. Bolotowsky’s mural for the Williamsburg Housing Project in Brooklyn, was one of the first abstract murals done under the Federal Art Project and is at the Brooklyn Museum.
