Hi all, I know absolutely nothing about trains. I found an old group of 57 photos of old trains while sorting through some boxes in my closet. The pictures were given to me by my great-grandmother just before she died, and I am guessing by the wear/quality that they are very old. The first picture in the set is titled "The Race of the Iron Horse and the Horse Car", and the last is a conglomeration of about 100 railway trademarks. This is obviously a set, as all are titled and numbered 1-57. Any information would be much appreciated! Thanks in advance!!
