13th Floor Elevators Original Concert poster 1st printing thirteenth floor

Original 1st printing of an iconic 13th Floor Elevators concert poster from the mid 60's. Poster is in very good condition (see pics) with some colour missing in a couple of spots. I am a collector and bought this a number of years ago from an extremely well-known and highly regarded rock poster dealer (collector/author). This is an original, not a repro and is the 1st printing.
