He returned to New York and in 1993 had his first solo act out at the Charles Cowles Gallery in SoHo, Manhattan, after which the Metropolitan Museum bought two of his paintings.
The Whitney Museum of American Art in New York bought one of his canvases in 2001, and the Museum of Modern Art bought three in 2005.
