Sand Frames, especially bigger ones that fit a Jumbo Card are not as easy to find as they used to. Here is a nice used rendering of this classic effect made from wood. It is in good condition with a small blemish in the middle of the frame towards the class. The wood was nicked there. As you can see in the picture. Nothing that would impact performance.
The glass area is approx. 7.5″ x 5.5″
With instructions and stand.
