Last summer I picked up a large lot of postcard sized glass negatives, many damaged, at an antiques market in Wisconsin. There were about 120 in all and they all appear to be the work of the same photographer who initialed some of the photos G.R.M. Given the size and subject matter of the photos my guess is he was a professional (or at least semi-professional) photographer specializing in postcard photographs in and around South Dakota. I think this lot was a mix of his professional work and personal photographs. I’ve scanned about 50 for your viewing pleasure- see them all here.
