Fascinating link- people really pay money for this stuff?
Not sure if such things exist based in UK- wouldn't have thought there was a market for hand painted backgrounds as they look completely unrealistic and even the computer printed ones don't look great. Creases and lighting would be fairly problematic as well- the objects don't exist so the light isn't going to interact in the same way.
Perhaps others have better knowledge of what's available as it's not a product I'd have gone looking for.
Personally I feel there are much better solutions- shoot your own backgrounds and transpose your photo on them. Shoot your subject on a chroma screen although if you have good software and watch your colours you can cut out from other backgrounds such as grey easily enough.
Alternatively, you could purchase some stock photos for use as a background or look for royalty free images to use.
I just think you would be wasting your money but it's your money.
