No, is not for sale.Maybe is my mistake, sorry.
I have better photos here.Too big for this site and technology and me, not good friends.In my time the microwave was a terrific discovery.
So here is the place to see better photos of the stamp.
I'm here to have advice. I will sell the stamp this fall, with all my other stamps in auction, but no $100 000 stamps.https://www.justcollecting.com/misc...-7-kop-nh-og
