Original 1st/only printing 12 x 18" concert poster for Martha Mushroom's Fantastic Sensations (great name!) with the United Empire Loyalists and the Painted Ship at the Afterthought in Vancouver, B.C., Canada on 2/210-11/1967 (also lists Country Joe & the Fish appearing "next week"...).

Art by (and signed in blue ballpoint by) Bob Masse (a VERY early signature). Medium thick flat stock poster is in fantastic near mint (A-) condition; only the tiniest of bends on the upper left corner, otherwise a sparkling example. A very early signed Masse poster with a real nice design/layout.
