Russian stamps overprinted "Z" in a box. Civil war?
by Jan-Simon Hoogschagen
Here is a new mystery for you. I hope you can help me identify these stamps. I can't find them in Michel, but suspect they are some kind of civil war issue. Thanks, Jan-Simon

This is the second issue of Armenia. The framed overpints were issued from November 1919 to January 1920. Since February to March 1920 similar overprints without frame were issued.

Analtoly is correct but should have added that these particular stamps you illustrate are common forgeries. For further details of forgeries and how to identify them see my handbooks, Vol.I. Parts 1 to 4.
