Initially it was a project for my friend. She wanted something with palettes. I came up with this Banksy stuff. Instead Lord Vader there was "Girl with Baloon". Recently I was browsing Google graphics with phrase "Banksy" and I found this amazing Lord Vader stencil. I had to recreate the project (just for fun) and this is a result. The funny thing is that, Lord Vader stencil isn't actually Banksy's. When I made little research, I found that it is created by KAMonkey.

The next funny thing is that, if it was really Banksy's work, it would be one of my favourites. KAMonkey is AWESOME!!!
