I was going through the covers at the local stamp shop on my weekly pilgrimage, and I came up on this cover. It was love at first sight.

I knew nothing about it when I bought it. Here is what I have been able to find out:
It is from the Ukraine, in 1993. The Ukraine had been liberated as a part of the dissolution of the USSR in 1991.
The stamps are denominated in karbovanets, which was the name of the Ukranian currency at the time. By the time 1993 came around this currency was in full hyperinflation.
Inflation for the year 1993 was over 10,000%. Thus it would make sense to print off stamps on the spot and hope the printer finished printing before the currency was revalued in the mean time.
What I do not know is exactly how much each stamp is worth (100 or 100,000 karbovanets?). Here is a closer look.

I do not know the significance of the box in the lower left hand corner with its dark bars and dotted, slashed squares.
Also, if anyone knows what it says on the back of the cover I would love to know too.

Happy collecting!
