Original 1st printing 7 x 11" double-sided flyer/oversized handbill for RCA Records' "Group Quake", a showcase featuring recent RCA signings Autosalvage, Group Therapy, Joyfull Noise and Status Cymbal along with the Joshua Light Show, held at New York City's legendary Fillmore East on 5/11/1968. Art by David Edward Byrd, this image is not part of the numbered Bill Graham series, although it does say "Fantasy Unlimited, c.1968 Bill Graham No. 7" in the lower left corner, leading to the conclusion that this was some sort of BG-sanctioned event; it was held the night after the BG FE-7 Jimi Hendrix/Sly and the Family Stone show, and is sometimes referred to as #7(A). Medium flat index/card stock flyer is in near mint (A-to A-/B+) condition; a touch of handling and a tiny bit of surface wear (a small mark in the bottom border), otherwise fine. Weird little original 1968 Fillmore East item, featuring a design reminiscent of the #5 Traffic/Blue Cheer/Iron Butterfly image.
