No, it is not a drawing nor a computer generated graphic. This is a photograph. The real photo of the real thing made by Randall Rosenthal, a carver from New-York.
But the most fascinating fact about this work is how Randall made it. The whole artwork including all the tiny pieces of onions, garlic, pages of the recipe book (opened on the wrong page as you can see) are the parts of the whole. Everything is cut out of the single solid piece of wood.
