Hanna-Barbera Production Logo (1966)

Description
Maybe from an old VHS of "Jack & the Beanstalk" (1966). The classic zooming-in HB logo (seen on Speed Buggy, the 1973 Superfriends, among others) was clearly inspired by this design. In turn, it gave way to the beautiful Rainbow H-B of the mid-1970s (and its smaller version in 1978). Not the worst thing going.
