I'm searching for a real photo print of the attached poor Stencil print which was published in SitRep no. 8 in April 1973. It shows 130 Glens in front of the Gerardus Majellaschool, Leliestraat 2a, Hilversum. I want to use the photo for identification of the Glens and finding their Surnames. Thank You.
