BG133 advertised four consecutive Fillmore West mid-week and weekend concerts. A triptych in design, Griffin used hand-drawn color plates to make 3-D images project from the background, and the frames of the panel appear to be insect legs. A collaboration between Griffin and Alton Kelley, the image's central figure may be the herald from Hell, a menacing image which contrasts with the bubble-infused, cartoon-style lettering of the side panels.
The 1st Printing poster is on mat uncoated stock. It lacks the notation described in the 2nd Printing. It was printed before the concert and measures 21 15/16" 28 5/16".
The 2nd Printing was printed on glossy stock and bears a Wolfgang's notation in the lower right-hand margin. It was printed in 2018 by Wolfgang's in a 500 copy run. It measures 22" x 28 1/2".
As a founding member of the Family Dog, Kelley handled promotions for the events at the Avalon Ballroom, drawing posters and handbills. He soon met up with Stanley Mouse, and their association nurtured Kelley's success as an artist. Kelley had a natural talent for collage and a keen eye for culling and combining imagery and styles from diverse sources. Teamed with Mouse's drafting skill, collaborations became increasingly sophisticated, yet irreverent. Kelley always worked by hand, producing posters and other print graphics for a wide array of entertainment-oriented clients.
