Cropped photo showing the camera bag the person in the glass plate is holding.
A similar looking bag found in the contemporary Seneca catalog for the Seneca 8.
Closeup of the object in the gentleman’s hand. I think it looks like a tripod.
A detail of a similar vintage folding tripod leg (manufacturer unknown) with stylish brass hardware similar to what you can see in the image.
I THINK this gentleman is holding a camera bag similar to this one from a contemporary Seneca catalog and a folded tripod similar to this unmarked folding wooden one from an eBay add.
