My father who served in the US army in WW II recently passed away. In his things I found an envelope marked Wiemar 1944, Consecration (sic) Camp. In it were several pictures of him in uniform, etc, but it also had several original pictures of a concentration camp. Large piles of stacked emaciated bodies, the ovens, what appear to be gallows, etc. I believe it was Buchenwald because of the Weimar reference. I would think that they have historical value if nothing else. I am a complete novice in WWII memorabilia and my first thought was to contact the local holocaust museum to ask about them. I see there is a thread on preservation of collectables, but I assume the museum could guide me about that. Do they have any monetary value? Any comments or gudance appreciated.
