Original 1st printing 14 x 8&1/2" uncut pair of handbills for Bill Ham's Light Sound Dimension (L.S.D.) Light Show appearing at the San Francisco Museum of Art from 2/3-5/1967, along with a small promotional for Stanley Mouse's Haight-Ashbury "dry goods" store, "Pacific Ocean Trading Company" (or, "POTCO").

 Art by (and SIGNED in pencil by) Stanley Mouse, image (another version of the Bill Ham portion) is featured in the Art of Rock book on page 238 (plate 2.361).

 Thin flat stock handbill sheet is in very good to excellent (B/B+ to B+) condition; there is a 1/2" edge tear and a small diagonal bend in the left margin, along with a light to moderate amount of handling wear/light creasing, a touch of toning, a couple of tiny pin-prick ink streaks here and there and a thin diagonal crease/bend along the upper left margin/corner, otherwise fine.

 Fairly unusual early-'67 Mouse item with a nice large signature.
