The title of this particular poster is "In the First Unit", printed at the top just below the name of the series. The poster features the first members of the elite Soviet cosmonaut corps that trained alongside Gagarin and were among the pioneers of the manned space flight program.
The bottom margin shows information about the publisher including the number of prints in circulation (just 3000 copies, a tiny number by Soviet standards) and the retail price of 1 Ruble (a typical cheap price from the Soviet era, before the runaway inflation that hit Soviet, and later Russian economy starting from the early 90s). This series of posters was published in 1990 ahead of the following year's upcoming 30th anniversary of the Gagarin's space flight. The posters were apparently created as educational tools, to be displayed in schools, libraries, museums etc.

The poster is in excellent condition. It shows only very minor wear to the edges, but no tears, scuffs, folds or any other significant damage. The colors are strong, not faded.
Please note that it will be shipped rolled in a sturdy cardboard box.
