Lot Cold War Soviet Union vintage postcards of Leningrad in cyrillic

2 folders of early 1970s unused Russian postcards with labeling in cyrillic. One package is of 16 postcards of - The Statues of the Summer Gardens - in Leningrad (St. Petersburg). They are dated 1973. The other packet is of 15 postcards of scenes of Soviet Russia. They are all labeled in cyrillic, so we're not sure what they are of. One shows an agricultural combine factory, others are war memorials or Soviet architecture.
