A signed A4 data sheet of Russian cosmonaut

Valeri Polyakov.

He holds the record at 438 days aboard the space station MIR, between January 1994 and March 1995. It would have lasted even longer, around 540 days, but the Russian Space Agency was unable to pay for the launch vehicle needed to return him, so he returned with an earlier crew.

Comes with a 12x8 photo of Polyakov

This montage is then double mounted ready for framing.
