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 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 are a series of stray handling dings scattered around the image area and a few minor edge dings here and there, but for the most part this example is pretty nice.
REALLY cool-looking little oddball SIGNED Mouse item from early 1967!
