When it came to creating psychedelic imagery, Lee Conklin had no peer. BG126 reveals more with each perusal, albeit revealing a lot of "ubiquitous breasts and butts" with every viewing. The first lineup featured two great blues-rockers, pioneering bluesman Albert King and Linda Tillery's Loading Zone, and the second headlined Ten Years After with virtuoso guitar player Alvin Lee and traditionalists Canned Heat.
The handbill measures 4 5/8" x 7 1/4" and displays a calendar of upcoming Bill Graham events on the reverse. It was printed before the concert.
There were also some pre-concert double-sized mailers printed that were conjoined with the BG125 image (see BG125/126). They measure 4 5/8" x 14 1/2".
Concert promoters created handbill versions of many of their posters and used them as sidewalk handouts and dashboard fliers to promote upcoming shows. Many of the handbills are double-sided, with poster art on one side and a calendar of upcoming shows on the other. These handbills represent an important element of rock concert history because they were hands-on marketing tools that united promoter and patron.
