Sleeping Dog at the Edge of the Rug, Irregularly Cut Antique Tintype Photo

Perhaps this tintype of sweetly sleeping dog was cut down from a full plate image, I'm not totally sure; it's a bit irregular in shape--and one can just see the edge of a what I take for a skirt and shoe along the right edge. Whatever the case, a pretty charming portrait of cozy contentment, and perhaps a good reminder to just be lazy sometimes! I especially love the uneven cut of the rug or mat along the front edge, revealing the wood floor below--maybe revealing the makeshift set up in a photographer's studio, a sort of behind the scenes moment. 

2 7/8" x 2 1/8", somewhat unevenly cut edges, with a few minor bends visible just when held at a certain angle.
