Chess Posters?

I've been looking for a good poster of a famous game or grandmaster. Or perhaps a photograph/picture of a famous tournament. Does anyone have any suggestions how to obtain one? I haven't had much luck with searching the internet

Do you have a particular game or grandmaster in mind?  There is lots of inspiration to be found here:

I did a goole shopping search. There is a paid/promo placement for allposters.com. I don't know if they are a good place or not but if you go there and search on chess you will find some. The 1st page has a poster of Bobby Fisher, one of Kasparov, and one of Tigran Petrosian.

thanks everyone for the ideas. I'll look at them and decide on one.
