Original 1st printing 14 x 28" boxing-style cardboard concert poster for Santana appearing with the Byrds at Memorial Hall on the campus of Muhlenberg College in Allentown, PA on 4/24/1970.

 Printed by Posters, Inc. of Philadelphia, thick cardboard stock letterpress poster is in decent/used (B/B- to B-) condition; as this example was removed from outdoor public display at the time of the show, it exhibits a bit of toning/staining/surface wear, along with numerous stray staple holes (several of which appear to have been hastily removed, leaving behind small wedge tears and creases), a modest amount of edge/corner tip wear, a few small tears/creases in the left center margin, a small 1" diagonal crack/bend in the upper right corner, a tiny wedge out of the upper left margin and a bit of moisture warp to the board... definitely a bit on the worn/used side, but I honestly can't say that I have seen another one.

 VERY scarce low-run regional Santana/Byrds concert artifact from Eastern Pennsylvania.
