Hi Bill, I put mine in a Richer mount (shadow box) but it's just for visible storage. The large frame of stuff my dad picked up to the D-Day Dodgers has each shoulder flash mounted with a museum certified sticky tab. The tabs peel off the fabric and background mat without leaving a glue residue. This stuff is pretty cool but expensive. I looked in my latest issue of the Carr McLean catalog
www.carrmclean.ca and the product is called Bienfang RagMount Adhesive. It is not cheap.
