Hello Leigia. Thank you for your appraisal inquiry with Mearto. The items presented appear to be albumen photographs of a group a people constructing a railroad line. One print is dated to 1937. The photographs do present some condition concerns. The edges are torn and there is quite a bit of discoloration. There does not seem to be any photographer studio copyright. Unfortunately, we cannot attribute the prints to a photographer at this time. The estimate provided is based on recent auction estimates for a small collection of albumen photographs of similar subject matter and age without photographer attribution. Thank you and please take care.
