Original 1st printing 8&1/2 x 11" concert/event flyer for the Helix/KRAB Media Mash, a multi-act benefit show (*for the Seattle Helix underground newspaper) held at Eagles Auditorium in Seattle, WA on 4/21/1968, along with the 4/28/1968 "Piano Drop" event (featuring Country Joe & the Fish) held in Duvall, WA (flyer also mentions Country Joe & the Fish appearing at Eagles Auditorium from 4/26-27).

 Art by Walt Crowley, image (poster) is image SFH 24 in Scott McDougall's "Split Fountain Hieroglyphics".

 Thin flat stock flyer is in excellent (B+) condition; aside from a small diagonal bend/pressure crease in the upper right corner, a touch of mild paper toning and a whisper of edge wear, it is a VERY sharp example of this EXCEPTIONALLY scarce 1968 Eagles Auditorium flyer, I have not been able to find any other examples ANYWHERE.
