This stereo view of a studio interior has no identification. It is printed on very heavy paper and is unmounted. Two men sit for a photographer with a large camera on a table-like base. A dog lies curled up on the left edge of the frame. The sky light and side light windows give illumination. What is the object over the head of the photographer? It appears to be a curtain on a wire that is bunched up and draped out of the way on the right side. This must be on the top floor of a multistory building since the wooden structure on the right, behind the photographer, is the railing next to the opening for a staircase to a lower floor.
