Thanks guys. The negatives are from the 40's and 50's. I'm looking for negatives that I can make prints from (up to 6x9) of regional railroads showing locomotives. I have two negs now, one from Hagerstown, MD and one from Washington DC. My idea is to make prints from these negatives to my artistic tastes just for historical purposes. I enjoy local history and I enjoy railroad history. At some point in time after I accumulate a decent collection of negatives and make prints from them it'd be neat to show them. And if someone was interested in purchasing one, that is where I was a bit confused. I mean how would these negatives get out on the open market if the original copyright owner actually cared about their importance or significance?
