Picked up some pictures at a Flea Market today. There from the 20s and 30s (dates are in corners of pictures). They are a very sturdy glossy print that has cloth backing. Looks like the May have been part of a bunch that were in a binder at one time. Each picture is stamped with "Edw Ruud Manufacturing, Philadelphia ". Does anyone have any insight on them? I plan on framing them. Thanks
