What is the seed of this Minecraft image?

If you play Minecraft, there is an excellent chance that you’ve seen this picture before:

This image is shown at the minecraft.net website. Just recently, I’ve been starting to wonder: is there a seed for this picture? All of the terrain in this image looks very natural. The trees in this image also have different patterns, so it is very likely that this is a real Minecraft seed, and Mojang just made this Minecraft seed into an art. I’m very curious – is there a seed for this world, or is there a world for this picture so that we can recreate the picture or play on this world?
