when the OS site first started up I tried to download the clubs emblum (cant spell it) as a background on my PC. I emaled the club asking them if they could tell me how I could do it. I recieved a real snotty email back spouting on about copyrights and comercial property rights, basically telling me to get lost. they also added a little write up on the site which followed the same line, so I know they are a bit possesive about things.
But. I am guessing.
They know people could down load and print of the poster. they would only be protecting cities intereasts.
Checkout a real one in the shop, I bet it looks a lot better
