Forest Wallpaper Help

Does anyone know if/where it is possible to purchase the forest wallpaper from the beginning of the film? Below is a screenshot of the scene in question.

After conducting my own research, I discovered
http://www.bigstockphoto.com/image-3174529/stock-photo-background-from-birch-trees-without-leaves

This leaves me under the assumption that it was just stock art bought for use in the film. However, in trying to tile the preview image myself, I realized that it isn't an exact tile which is probably a result of a less than perfect scan job from a clipart book. So this leaves me with 2 questions...

Does anyone know where to get cool wallpaper similar to the one used in the film?

Does anyone know where the original image came from? (I would bet that the original was the inverse of these colors)
