I found this in a bin at a local antiques faire a week ago. The cool part is the first baggage car, right behind the locomotive, is the baggage car we are restoring at NWPRRHS.ORG, seen here . By identifying the locomotive #21, which was a number only used by the San Francisco & Northern Pacific RR, a predecessor to the Northwestern Pacific RR, we know that this was taken between it's build date of 1892 and when it was taken over by the NWP in 1907.
