Wink Tennis

Instruction manual introduction:

Here's a new "portable" table tennis game whose lively action folks of all ages enjoy, from the five-year-olds up to the adults in the family! It has the came [sic] court and the same scoring as table tennis, but you "snap the Wink" instead of hitting the ball. The Wink-on-a-String never gets lost, so WINK TENNIS can be played anywhere, even on trips or when sick-a-bed, etc. Two players can play Singles; or 4 players can play Doubles.
