Original 1st printing 14&1/8 x 19&7/8" concert poster for local SF psych-rockers the Universal Parking Lot appearing at the Matrix in San Francisco, CA from 12/9-11/1966. Designer unknown, medium-thick flat vellum stock is in very good to excellent (B/B+ to B+) condition; a fair to moderate amount of handling wear/creasing along the left/bottom margins with a few stray semi-pronounced light bends and a stray surface scuff or two here and there, otherwise not too bad... a very unusual oddball early Matrix poster with an amusing design.
