4 volume set of books

I inhieted a set of four books from my father. The closes I came come is that they were printed by the VFW in 1948. The name of the books are
"Veterans of Foreign Wars edition Pictorial History of the Second World War."
They had been stored in a cardboard box in a garage and are not in real good shape on the outside. It is a day to day account of the War in pictures. Has anyone ever heard of the books and does anyone know what I should insure them for? I do not want to sell, just information on them. Students enjoy looking throught them.

 

Thanks, I found what I needed.
