Original 1st printing 12 x 18" concert poster for Martha Mushroom's Fantastic Sensations appearing with United Empire Loyalists on 2/10/1967 and with Painted Ship on 2/11/1967 at the Afterthought in Vancouver, BC (Canada) *poster also lists Country Joe & the Fish coming "Next Week!" along the bottom edge

 Art by (and SIGNED in ballpoint pen by) Bob Masse (very early signature), medium flat index stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a couple of VERY tiny handling dings and a soft corner-tip bend or two, it is a fairly clean example of this oddball Masse poster from Vancouver.
