My folks bought me this from this Edmond Scientific in 1965 or 1966. Despite much misuse in childhood like throwing it as a dodgeball at my brothers and other unsavory acts it has survived and is roughly 55 years old. Any of the other old codgers here have one of these?
Why waste your time outside battling humidity and mosquitos when you can sketch this in the comfort of your own home? It's hard to see, but the bottom half (darkside) is filled with moon facts. The abuse adds a kind of wear and tear patina that mimics the wear and tear on the moon itself. I'm also including the ES catalog entry.
