Original 1st printing 13&1/2 x 21&7/8" cardboard concert poster for the Seattle Summer Jam, a one-day event featuring performances by Bachman-Turner Overdrive, the J. Geils Band, the Charlie Daniels Band, Flash Cadillac and Bob Seger at the Seattle Center Memorial Stadium on 7/27/1975.

 Design by/printed by Train Printing & Poster Co., thick cardboard stock poster is in excellent (B+) condition; there are a pair of approximately 1" soft indentations/bends in the right margin, along with a couple of tiny corner tip creases, a hint of surface wear (a couple of tiny scuffs/pin-prick spots) and a tiny drag pull on the reverse, otherwise fine.

 Really neat-looking regional cardboard poster from "The First Major Outdoor Concert In Seattle In 5 Years". I'm guessing there were probably quite a few Camaros and Trans-Ams in the parking lot that day.
