Original 1st printing 17&1/2 x 24&1/2" concert poster for Santana appearing with American Dream at  the Mayser Center on the Campus of Franklin & Marshall University in Lancaster, PA on 3/13/1970.

 Designer unknown (show was partially sponsored by Ballantine Beer as part of their "Three Ring Thing" series of concerts), medium flat vellum stock poster is in good (B) condition; pin/tack holes and clear tape remnants in all four corners, with a couple of additional slivers of tape in the left/right/top center margins, plus a 1&3/4" tear in the top center margin (taped on the reverse), another 3/4" tear in the bottom center margin and a series of light handling dings/thin roll bends, otherwise fine. There are a couple of areas of slight discoloration (it looks like someone had affixed heart-shaped stickers) in the left center/lower right margins-they can be seen pretty clearly in the photo, I'm not sure if this is supposed to be part of the design or not, but I'm mentioning it anyway, to be safe. 

 VERY unusual oddball low-run Santana poster from a small central Pennsylvania college show.
