Artist-signed postcard depicting the famous album cover art for ''Sgt. Pepper's Lonely Hearts Club Band'', designed by Peter Blake and Jann Haworth, who each sign. Just as the album advanced the boundaries of rock music in the late 1960s, so did the cover art for ''Sgt. Pepper'', showing The Beatles as an imaginary brass band leading a parade attended by 20th century historical figures. Royal Mail Stamp Collection postcard measures 5.875'' x 4.125''. Near fine condition.
