Strange Soviet bonds
City of Kazan Cleanliness and Beutification Loan. It looks like a bond, it’s called a bond but it’s not a bond as we understand this term.
It is a lottery ticket – holder of this ticket was obliged to work for 2 days for the City of Kazan, his performance was confirmed by stamping or validating 4 half-daily coupons attached and this “bond” with all coupons validated entitled the holder to participate in a lottery with a chance to win 10.000 rubel prize.
