While I was digging out the photographs of the Big Horn Sheep diorama I came across this pair I took of the Cold Bog Diorama, also at the Yale Peabody Museum (also by James Perry Wilson). You can see more about this diorama here and here. In the second of these links is an assembly of Wilson’s survey slides. Here (below) is the same assembly done in Bridge/Photoshop, somewhat dissolving the frames and compensating for the faceted picture plane as Wilson’s Dual Grid method would.
See two posts below for advice on viewing stereoscopic pairs (for the top image).
