I have been rummaging through some of my Grandfather's belongings, a WW1 veteran, and came upon a set of photos. Obviously professionally done, I am looking for any assistance to help identify what these WWI photos are part of - ie. is this a collector set? There are (11) 4x3 inch cardboard photos of various scenes of the war with description of each photo on the front and nothing on the reverse, probably held onto by my family through the years. Any help in identifying this set, are they part of a bigger set, and if there is any market value towards these photos would be greatly appreciated.
Thank you, Dan
