Original 1st printing 4&1/4 x 5&1/2" thin paper blank-reverse concert handbill for an April Fool's Dance Concert and Costume Ball, featuring appearances by the Sparrow (proto-Steppenwolf), the Orkustra, the Outcasts, Santana ("Bluz") and the Hedds, held at California Hall in San Francisco, CA from 3/30-31/1967.

 Designer unknown/not credited, thin flat stock (WHITE stock version) handbill is in near mint to excellent (A-/B+ to B+) condition; other than a tiny diagonal bend in the lower right corner tip and a nearly-invisible handling ding or two, it is a VERY clean/sharp example of this obscure (and EARLY!) Santana concert artifact from California Hall.
