I have these three cut squares in my collection for some time and I am not sure about them.
the paper is green, but it should be blue, so I guess this is a "greenish" blue?
I thought this would be white war paper, but for die 146(H) this would be too late? So is this just white paper?
the indicium is black if you look at it like this. Also under magnification (120x) it's hard to find any blue in it. Is there a dark blue or blackish blue variety possible for this stamp?
Thank you for your help.
