This is a fast food style double cheeseburger created with Cycles. There is only one photographic texture for the tomatoes. That photo I took of a tomato I bought and sliced. There are a few simple black and white image masks (the Bun gradient, the grill marks) which were created by hand. There is no outside art of any kind in this Blend, and you are free to do whatever you like with it.
I created it over about 4 weeks total, and toward the end relied heavily on feedback from screenshots I posted on BlenderArtists.com. Special thanks to Lancer and Minoribus for catching details I wasn't seeing any more.
The a-Master-Cheeseburger-Empty can be used to move/rotate the entire cheeseburger.
You can append the scene (including lights etc..) as: Scene-Cheeseburger
Or there is a Group you can append of the Cheeseburger alone: Cheeseburger-all
