a.k.a. Color Matcher
Circa 1980's?
(2.9" by 1.5" high plastic box and seven hexagonal plastic pieces)
Arrange the seven hexagons so that adjacent edges match. Like the Circus Seven puzzle, but a smaller size puzzle with different color patterns. Jaap's Page shows a number of other color variations for which this puzzle was made.
