Bonhams' upcoming Space History Sale -- happening May 5th in New York -- is filled with items that will make any space geek reconsider their current spending priorities, but we couldn't help but notice one particular item that hits a little closer to home. Mixed in with spacesuits expected to fetch upwards of $100,000 and other various memorabilia from both the US and Soviet space programs in this, a wholly ordinary Nintendo Game Boy (complete with Tetris, of course) that accompanied cosmonaut Aleksandr A. Serebrov on Soyuz mission TM-17 in 1993. Interested? The estimate is pegged at a somewhat reasonable $1,500 to $2,000, but we have a sneaking suspicion Bonhams might be underestimating the will of a considerable number of folks who are both space and video game nerds (we're speaking as one ourselves, of course). Hit up the source link below to check out everything up for auction.
