Abba-Zabba, Overprint (BG-253 & BG-254)

This remarkable overprint from Bill Graham's Fillmore West operation captures a moment never meant to be preserved: the chaotic beauty of the printing press mid-production. Combining elements from BG-253 and BG-254, two late 1970 concert posters, this sheet layers a striking orange and black checkerboard design against circus-themed imagery of a whimsical clown figure. Overprints emerged when printers ran test sheets or cleaned their presses between jobs, creating accidental compositions that merge multiple poster designs into singular, unrepeatable artworks. This example showcases the visual language of San Francisco's psychedelic poster scene, with its bold color combinations, surreal imagery, and distinctive Bill Graham typography. A compelling piece of Fillmore history, this overprint offers collectors something rarer than any standard concert poster: a one-of-a-kind document of the creative machinery that powered rock's most legendary venue.
