Five of the seven hold plastic instruments, one has congo drums and bass drum, and one has two plastic balls in hands. A lightbulb is in each corner. Originally issued in wood and glass case with coin mechanism. Dime operated machine was a musical novelty and played three songs in a Mexican musical style.
