From 1957 to 1960, he earned his living as a billboard painter. This was perfect training, as it turned out, for an artist about to explode onto the pop art scene. Rosenquist deftly applied sign-painting techniques to the large-scale paintings he began creating in 1960. Like other pop artists, Rosenquist adapted the visual language of advertising and pop culture (often funny, vulgar, and outrageous) to the context of fine art. Rosenquist achieved international acclaim in 1965 with the room-scale painting F-111.
Rosenquist has said the following about his involvement in the Pop Art movement: “They [art critics] called me a Pop artist because I used recognizable imagery. The critics like to group people together. I didn’t meet Andy Warhol until 1964. I did not really know Andy or Roy Lichtenstein that well. We all emerged separately.
