For the last four years, I have researched every aspect of this self-portrait to confirm its artist identity!! Today, I can confirm the artist of this self-portrait, it is ROY FOX LICHTENSTEIN!! I was able to match the 1956 signature to the “rather primitive notion of patterned linear repetition”, or unknown markings (which look like Hebrew) on the side of an airplane in the RFL’s drawing “AIRPLANE 1961”. Similar markings can be found on the RFL’s TEN DOLLAR BILL 1956 Lithograph. The signature on the TEN DOLLAR BILL is written in reverse (use mirror image)!! The self-portrait was purchased from the Alfred Bader Fine Arts Collection in 2008, and Mr. Bader purchased the self-portrait from the Wolf Auctions by a sealed bid in Cleveland, OHIO in 2000!!!The Masters of POP ART were Andy Warhol and Roy Lichtenstein!! This art find shows the true genius self (RFL) as influenced by two great artists, Pablo Picasso and Vincent van Gogh!! This unknown 1956 self-portrait shows the true image of the master in an insightful and emotional representation of the artist (RFL)!!!It has been over 50 years since these two paintings have been together. The art of Roy Lichtenstein which pre dates 1960 is super rare. These two paintings represent a period time just before his sucessful run in Pop Art. Please refer to the individual paintings listed for more information. During the period of 1950-1957 RL's paintings and drawings were parodies of American 1920's art.(e.g.Remington). Then from 1857-1960 his work passed through a non-representational, Abstract-Expressionist phase. In 1960 he became one of the most acclaimed POP Artist along with Andy Warhol(1928-1987). RL's early period of art was influenced by Pablo Piscasso(1881-1973), George's Braque(1882-1963), and Arshile Gorky (1905-1948).
