Posters from Book covers..?

[EchoEffect]

I really want a poster of one of my favourite book covers. However I can't find any on the internet :P. There are sites and shops that make posters from any image, however I'm not sure of copyright laws and things that would be affected by this...

um...help please :dunce:

It would help if we knew the book's title, author and the like :-)
Then maybe I could do a quick search. Try www.allposters.com
