RARE 1979 Beach Boys Caribou Records Hanging Store Display Advertisement Mobile. I got this in an estate buyout with some Records. It is in good shape, doesn't really look to have ever been assembled. Not exactly sure how it goes together. It was It stored away as you see it and labeled Display.

Can't find another one out to compare it to.
