Valentina Tereshkova signed Russian cover

Valentina Tereshkova signed 1990 Russian space cover with a 2nd December launch day postmark of the Soyuz TM-12 mission. This was the mission which took Helen Sharman into space. Tereshkova was the first woman in space, having flown a solo mission aboard Vostok 6 in 1963. She orbited the Earth 48 times, spending almost three days in space.
