RAILWAY TRAIN CAR CABINET CARD PHOTOGRAPH 1535

LARGE 5x7 image size on a 8x10 card mount.  Great image with decent focus.  Not sure where 1535 was from.  A second train can be seen behind the first but there are no numbers visible.

Minor staining on left lower edgeand usual bumps from age.  Great image for a train enthusiast...any Sheldon Coopers out there?
