People have been visiting space for 50 years now. There have been many hundreds of different flights made and more than 500 astronauts have been to space. From these flights there are a number of patches, stamps, and other memorabilia made. Astronauts have also been in number of photographs. All of these can be purchased now

Some of the best places to purchase are for example http://www.space-boosters.co.uk/ and Ebay. If you search Ebay with "space" you can find more than 800 000 different items. I have bought some myself patches, one Yuri Gagarin medal and stamps. Astronaut autographed picture is the next my list. In the Spacebooster there is for sale for example Afghan cosmonaut Abdul Mohmand autographed picture for £ 9.99. Not bad. Neil Armstrong autographed picture costs much more. Those you can find from Ebay.

Below is the Apollo 17 flight patch, price £ 5.00.
