There were several sets of lithographs in Russia in the 70s and 80s.This one you list was made on the basis of drawings of a Soviet artist. Others showed the cosmonauts in military uniforms or space suits.
They were tremendously popular and often only available with good contacts. At the same time, at that time, they were practically the only photographic material that one could get to have the cosmonauts autograph them. In the 60s and early 70s, there were also sets of postcard portraits.
At the time, the interest in these cards were mainly to have them signed by the cosmonauts. Today, most of these veteran cosmonauts are no longer with us, which limits the interest. If you wish to buy such a set, you should primarily be interested in the photo portraits themselves.
