 Medium flat vellum stock poster is in VERY sharp near mint (A- to A-/B+) condition; aside from a couple of tiny rub marks in the upper left corner and just the slightest hint of handling wear, it is an absolutely GORGEOUS example of this very bright and charming little 1967 Big Brother poster from Santa Clara.
