Original 1st printing 11 x 17" concert poster for Johnny Winter with Tin House at the Boston Tea Party (15 Lansdowne St location) in Boston, MA on 9/17-19/1970. Art by Eric Engstrom, medium flat index stock poster is in excellent (B+) condition; a flattened soft horizontal center fold, a couple of ultra-soft diagonal bends in the lower left corner and a whisper of handling, otherwise fine. Awesome-looking Johnny Winter poster from one of the later Tea Party concerts, not a common one.
