Original 1st printing 3&5/8 x 5&1/4" blank-reverse concert handbill for the Grateful Dead appearing at the Portland (OR) Coliseum on 6/24/1973.

 Design by Pacific Presentations, medium-thin flat vellum stock handbill is in near mint (A-) condition; aside from a tiny pin-prick rust spot in the left center margin, this example can not be improved upon... a VERY sharp specimen. Check out the show HERE:
