Хронология советских марок за 1975 и 1976 гг.

I propose a chronology of postage stamps of the USSR for 1975 and 1976. This lot includes two years. If the buyer wants to buy one year, then he must make one bid, if two years, then make a bid twice. It is desirable that the buyer inform me what he wants to buy, in order to avoid misunderstandings. This lot has rare art stamps with coupons. These are Ulyanoa, Fedotov, Yuon, Such stamps are very difficult to find, even at Russian auctions. The total value of the exhibited stamps for two years is about 5.0 thousand rubles If you have questions, suggestions, write
