Pair of official (promoter-issued) reprint (RP-2 and RP-4) 14 x 20" (appx.) 1966 concert posters for the 13th Floor Elevators appearing at the Avalon Ballroom in San Francisco, CA.
 
 Art by Stanley Mouse and Alton Kelley (Mouse Studios), images are numbers 24 (9/2-3/1966, with the Sir Douglas Quintet) and 28 (9/28-10/1/1966, with Quicksilver Messenger Service) in the Family Dog/Avalon series.
 
 Medium flat index (FD 28) and medium-thick flat vellum (FD 24) stock posters are both in near mint to excellent (A- to A-/B+) condition; they both have a few light handling creases scattered around the outer margin area, but overall both pieces are in VERY nice shape.

 Great-looking set of early Mouse/Kelley-designed 13th Floor Elevators images from the Avalon, a perfect set for the casual collector/fan.
