Here is a cute poster I made for my bathroom that is decorated in Harry Potter. It is 16x20 and feel free to save it for yourself : ). Just right click on it and "save as". You will need a poster making program to print it out on 4 pieces of 81/2x11 paper then piece them together, I use this one. It is a Shareware program but you can make 10 free posters before you have to register it : ).
