Antique Jesus Shepherd Sheep Stained Glass Pewter Frame Suncatcher Window

The suncatcher is in very good condition with no chips, cracks or breaks in the frame. There appears to be moisture or something in the glass or possibly between the two panes of glass, and I'm not sure it's made with two panes but it's thick. Whatever is is you can't see it when the light is passing through. It's heavy, weighing about 1 1/2 lbs. See Pics.
