Circus Seven

a.k.a. Mind Exerciser
Masudaya, Japan, circa 1980's?
(4.25" by 1.75" high plastic box and seven hexagonal plastic pieces)

Arrange the seven hexagons so that adjacent edges match. Like the Circus Puzzler, but a larger size puzzle with different color patterns. This is the same puzzle as Drive Ya Nuts, (the colors red, green, blue, yellow, white, and orange correspond to the numbers 1 through 6).
