Eric Burden made his first trip to the States to play this concert with Chuck Berry. BG070 was Greg Irons' first poster for Bill Graham, a relationship which lasted for only seven more posters, and he completed the rush job overnight.
The poster was only printed once prior to the concert. It measures 13 15/16" x 21 1/2".
Irons moved to San Francisco in 1967 and roamed around Haight-Ashbury with his sketchbook, creating images he would later use in his posters. As usual, promoter Bill Graham needed a poster in a hurry, and Irons succeeded in producing one overnight. As his talent as a draftsman developed, a distinctive line quality and refined sense of balance set Irons' posters apart. His cartoonist inclinations are often evident, and he became one of the seminal figures in underground comics. Irons also found work producing album graphics and book illustration, but it was the art of tattooing that became his passion.
