Duncan Bang-a-Ball two-handed award patch from the early 1960s.
Duncan Bang-A-Ball was not a yo-yo, but rather a paddle ball toy, part of Duncan’s broader product line during the mid-20th century. The player would hold the paddle and try to hit the attached ball repeatedly, keeping a rhythm. Marketed as "The Return Ball with the Bongo Beat!". It was often sold as a skill toy, similar to how yo-yos and tops were marketed — with the emphasis on developing hand-eye coordination and performing tricks.
