This set is a little different than Presto Magix and later Rub n’ Play sets. You had to rub pieces of a character or vehicle into an outline, which you would then prop up in a slot.
I believe the Rub n’ Play line started in 1978, as did Presto Magix. I’ve also seen Spider-Man, Mickey Mouse, and Hollie Hobby sets from the same year.

Love how the graphics on the box are exactly like Kenner’s Star Wars packaging, even the rounded border.
