Original 1st printing (West Coast Litho credit) 13&5/8 x 20&1/2" concert poster for the Grateful Dead with Chuck Berry and Johnny Talbot and De Thangs at the Fillmore Auditorium and Winterland in San Francisco, CA from 3/17-19/1967.
Art by Wes Wilson, image is # 55 in the Bill Graham/Fillmore series.
Medium flat index stock poster is in absolutely UNBEATABLE mint/near mint to near mint (A/A- to A-) condition; aside from a tiny print hickey in the left margin (just to the left of the "G" of "Grateful", this example is just about as sharp/clean as they come.
As a note of provenance, this example was actually given (along with several other posters we are offering in this sale) by Bill Graham himself to a member of his extended family back in the 1970's or '80s. Impeccable lineage!
