This is a Circa 1970s Vintage Sambo's Restaurants—Wham-O FB1 mold Square Top Frisbee Flying Disc. Color is white with red hot stamped Sambo's tiger logo. It is a used disc in fair to good condition, with some nicks and scratches on the edge and underside of the Frisbee. Square top FB1s were first produced in about 1974. They replaced the "Starjet" style fastback which debuted in 1971, and then were replaced by the more common round top fastback characteristic of the late 1970s and 80s.
