Last and most interesting Czech stamp of the series, 1963. The illustration of the spacecraft is a bit embellished from the actual design of the Vostok 5. Still though, it’s a great illustration.
This stamp must have been issued some time post-June as the correct dates for the mission are in the illustration. The mission was originally planned to encompass 8 days but was forced to end early when the waste disposal system stopped working. Regardless, the record for longest solo spaceflight was set on this mission and still stands.
