Lot of 6 old photographs on silver paper 1910-1920 military men

This pretty set of 6 old photographs is made of cardstock and silver paper. These photos represent men, including soldiers, and families, and date from the years 1910 to 1920. They measure between 11 and 14 cm wide X 9 and 17 cm high. I point out traces of use (folds, wear).
