Маркированные Почтовые карточки СССР .Плюс почтовые карточки

I offer a rare catalog. The catalog is called Marked Postcards of the USSR. A few words about this directory. This is one type of collecting philately. Along with postage stamps, they collect into whole things. i.e. envelopes, postcards, letterheads, etc., issued by official organizations. If information about postage stamps can be found in catalogs, then there is very little information about whole things and information can only be emphasized from the information published in the philatelic periodical press. This catalog is the result of many years of work of the Leningrad philatelist Listov \ The catalog includes postcards issued by the People's Commissariat of Posts and Telegraphs of the USSR People's Commissariat of Communications. In the USSR, from 1920 to 1990, only two catalogs were printed, this one and the catalog edited by F, G CHUCHIN, but this catalog was published in 1928. I would also like to add that the marked postcards are cataloged by the German catalog Michel. Some postcards from this catalog are recognized as very rare and worth a lot of money. This catalog contains Postcards from 1923 to 1979. In this lot, I included cards from 40-50 -70 and 80 years. Also included in this lot is a continuation of the postcard catalogs with original stamps. This catalog was printed in the late 80s and covers the period from 1971 to 1988. And it is an addition to the above catalog catalog. Catalog name SINGLE-SIDED POSTCARDS WITH ORIGINAL STAMPS 1971-1988 This catalog has 168 pages. Some of the cards displayed are included in this catalogue. If you have any questions about the proposal, then write, I will try to answer
