Hungarian stamps with black overprint Posta Romana 1944
Overprinted by order of the postmaster with a handstamp carved by hand in wood. According to the Sighet protocol, the handstamp was burned after overprinting. Printed in black ink which generally bleeds through to the back of the stamp. All stamps in greenish-black ink (blue-green from the back) are forgeries. No covers or genuinely used examples have ever been found.

Ten copies of the Red Cross 30+30 and 50+50 were also
overprinted, but never sold at the PO, and are comsidered proofs.
