Perhaps his most famous work was a painting entitled Convergence, which was a collage of colors splattered on a canvas that created masterful shapes and lines that evoke emotions and attack the eye. The painting was created in 1952, and is oil on canvas; 93.5 inches by 155 inches (Karmel, 1999). With Pollock's brushstrokes he was able to make handy use of colors, lines, textures, lights, and contrasting shapes. This painting is enormous and its size can only really be appreciated in person. In 1964, puzzle producing company, Springbok Editions, released Convergence (Inspired by Pollock's painting) the jigsaw puzzle. It was a 340-piece puzzle that they promoted as "the world's most difficult puzzle". The impact of Pollock's Convergence was evident in 1965 when hundreds of thousands of Americans purchased the jigsaw puzzle.
