Are there any LEGO movie/game posters? I'm trying to find some posters for my childrens room and everytime I find something on EBay etc .. they are all A4 or A3 :(

I'm guessing it's a simple process as getting a nice quality version image and paying a Copy/Printing shop to print one in A2 or A1.

Does anyone know of any links to Lego movie posters that are in a quality that is acceptable for such a high print?

Or links to shops already selling em?

Sample images: 

Clones Wars, Indiana Jones, Harry Potter, BatMan, LOTR.

As this is for personal use (sigh - I can't proove that unfortunatley :( ) that I shouldn't have any issues with copyright etc?

Appologies: for not having enough rep to create valid/accurate tags.
If you subscribe to the Lego Club (availability depends on your location) you will receive the official Lego Magazine and often a free poster is included. The March/April 2014 edition contained a reversible poster with the Lego City theme on one side and the Disney Princess theme on the other side.

Occasionally, you may receive promotional Lego posters with some purchases at the Lego Shops (or online shop). Brickset lists a few of these here.

Bricklinks is place where you could purchase posters that are no more available from Lego. Here is a list of all posters on Bricklink.
