Original 1st printing 14 x 21" concert poster for SF ballroom favorites the Sons of Champlin appearing with Mixed Blood and Gary Ewing's Light Show at the Portland (OR) State University Ballroom on 1/25/1970.

 Art by Catherine Weinstein, medium-thick glossy-coated index stock poster is in near mint to excellent (A-/B+ to B+) condition; just a couple of thin vertical surface scratches/scrapes in the lower left/right corners/margins, a tiny edge nick in the left center margin, a tiny corner bump or two and a few ultra-thin surface scratches and soft handling dings scattered here and there, otherwise fine.

 A great-looking psychedelic Sons poster from Portland, check out this EXTENSIVE gig list/history of the Sons of Champlin during the late '60's HERE:
