Wham-O shops Magic Window Vintage 1970s

Product Name: Wham-O shops Magic Window Vintage 1970s
Vintage Wham-O magic window sand art toy. This was used by me and my two brother's growing up, and is well played-with. Works as it should. The plastic around the edges shows a little bit of yellowing, and some drop marks, seen in the pics. There are some scratches on the face. Still cool to use and see what can be made. Neat item. Approximately 1973. Considering shops these in the original box for for $300+ as they are highly collectable. I think my price is fair for it's condition. But please make an offer.
