This double-sized postcard mailer was printed once before the concert. It conjoins the images from BG193 and BG194 and presents a calendar of upcoming Bill Graham events on the reverse. It measures 6 7/8" x 9 3/8".
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.
