Original 1st printing 5&1/2 x 8&1/2" concert handbill for the Grateful Dead appearing with the New Riders of the Purple Sage at the Santa Rosa (CA) Fairgrounds on 12/12/1970. 

 Art by Stanley Mouse (portraits) and Timothy D. Dixon (lettering/layout), image is featured in the Art of Rock book on page 364 (plate 4.96).

 Medium-thin flat stock handbill is in BEAUTIFUL near mint (A-) condition; aside from a tiny edge bump/ding in the top center margin, a trio of pin-prick spots in the "T" of "The" and a whisper of handling/surface wear, it is an ULTRA-crisp unbeatable example of this late-1970 Grateful Dead concert handbill.
