This is Archives Week and the Saskatchewan Archives Board has a project for us all to work on. They are posting a number of photographs from their files asking for the publics help in identifying people, buildings and scenes that they haven't been able to. This particular photo is from 1915 and is the Rosthern Home Guard, but none of the members names are known...maybe the little guy on the drum is your grandfather!  Here is the link to the Archives page with more mystery photos from around the province.
