I found these in an old album that I am breaking up. There were a few good older Great Britain items, then I came across this one. It has pencil marking on the back, "this stamp is scarce". I'm not holding my breath ...

This next one is even odder. Almost as if a piece of foil was rubbed into a part of the surface, then part of it cut away.

And this is stuck to the back. Any ideas?
