Are those wads of silver foil in the pictures? It looks like plain old Reynolds wrap to me.

I'm betting it's regular old aluminum wrap, and not edible. I was just pointing out that edible precious metal foils were available during that era. Just not for lining pans. ;)

BTW, using those super-thin precious metal foils is a serious PITA. I generally use a damp artist brush to apply them, since they tear so easily.
