This is heavily postmarked in MAR 1884. I can only make out CEM on the left and KO at the top. The value is 7 of something. Please help me to identify this one!
It is probably Russian as the writing around the edge translates as seven kopeks. But you can't be sure as Russia had their fingers in a lot of other nations pies.
It looks as if it has been cut from a pre-paid envelope.
