It's a Beautiful Day Postcard
The third and final Kelley and Griffin collaboration [BG133 and BG146 were the others] was a good example of both artists' use of contemporary advertising in their design. The Abba-Zaba candy bar wrapper was an interesting modern cultural reference and played a bigger part in the poster than the advertising for It's A Beautiful Day, Deep Purple, and Cold Blood.
The postcard was only printed once before the concert. It measures 4 5/8" x 7".
There were also some pre-concert mailers printed that were conjoined with the BG146 image. They measure 7" x 9 1/4".
Rick Griffin grew up in the surfing culture of Southern California, a milieu which had a profound influence on his art. After high school, he worked on the staff of Surfer magazine and created the best-known surfing cartoon character of the time, Murphy. After his move to San Francisco in 1967, be began combining eclectic typefaces and decorative borders with brilliant colors in his concert posters. Griffin's compositions were complex without being illegible. A perfectionist, Griffin often applied dozens of overlays and redrew lettering again and again until he was satisfied. In the early 1970s, Griffin became a born-again Christian and religious themes dominated his work until his death in a motorcycle accident in 1991.
