Hello all, I recently inherited a collection of Baldwin Locomotive Works photos (approx.60). I need help to identify what I have. Some of the photos are embossed with "Baldwin Locomotive Works, Burnham, Perry, Williams,& Co., Philadelphia, PA." in the upper left corner but most are not. The photos are of 1870's engines. The paper is a light almost magazine quality, not photo paper as I expect it. The pics measure 8 x 5. See below any thoughts
