Jackson Pollock's exciting drip and splash painting style opened new doors for Abstract Expressionists - and made for a formidable jigsaw puzzle! His spectacular Convergence oil on canvas from 1952 was made into a 340-piece jigsaw in 1964, and was hailed as "the world's most difficult puzzle." Our newly produced Jackson Pollock Puzzle nearly triples the challenge with a delightfully staggering 1,000 pieces! What a marvelous activity for art-lovers, puzzle pros, and the ferociously patient. Measures 29"x20" when (er, if) completed.
