My great, great uncle Robert F. McKee, Sr., was a design engineer at Baldwin Locomotive Works and he would give my father different Baldwin Locomotive builder's cards when my father would visit him in Collingswood, New Jersey. Here is a beautiful engine he helped design, the M-1 class 2-8-4 for the Louisville & Nashville Railroad. This Baldwin Locomotive Works builders photo card is from the John R. Doughty collection.
