I'm looking for a pencil drawing of a modern engine for the background of my website. I would like the image to look old fashion but depict a modern engine. The engine doesn't have to be branded with any manufacturer, in fact it would be better if it wasn't. Ideally the engine would be a V8 V10 or V12. A cutaway or transparent portion showing the working of the engine would be ideal. Something similar to the image attached but without the obvious brand marking would be ideal.
Obviously i would like the image to be a unique piece of artwork that i can own the copyright for.
