Original 1st printing 13&3/4 x 22&1/2" concert poster for SF favorites the Sons of Champlin with local openers Portland Zoo and Total Eclipse at Springer's Ballroom outside of Portland, OR on 7/4/1969. Art by Jim Blashfield, medium-thick flat index stock poster is in good to very good (B to B/B+) condition; a 1" tear in the top center, a set of pin/staple holes (all four corners), a couple of soft horizontal bends running from the lower right center margin to the center of the image, a light stain at approximately 3:00, a small bend in the upper right corner and a few scattered handling dings, otherwise fine. A great-looking psychedelic Blashfield image from Portland, check out this EXTENSIVE gig list/history of the Sons of Champlin during the late '60's (including this very gig) HERE:
