Sir Peter Blake, Alphabet, letter A, n.d. Source
In the 1950s, Blake began using ‘found letters’ or commercial lettering in his work, as well as printed materials such as comic strips and advertising texts, allying himself with sign painters, decorators, and commercial artists. Declaring himself a ‘pop’ artist, he joined the ranks of Lichtenstein, Rauschenberg and Rosenquist, in their provocation of the fine art establishment. He is famous for the cover of Sgt. Pepper’s Lonely hearts club band.
