Expected Penny

This print is on a different sort of paper than any I've seen.
The painting is so realistic from the little girl waiting for the old man, to the dog laying over to the side.
A piece of the glass has been broken off, so I need to put a new one in it.
The mat has some writing on the corner that look like initials. I wonder if it could be a signed copy.
The signature is _._. DODSON OR DOBSON on the lower left corner.
