It is a cars spray paint art, I watched a Mexican artist called Miguel (or Manuel) paint it on the side walks of Toronto in from of a big crowd of admirers. I purchased that one, and a few others of a similar genre. He is heavy on the pyramids concept, and early visitations. Gave away most of them. I gave this one to a young man from Serbia who has published two books on extraterrestrials visiting Earth. Took a picture of it before giving it away because I liked it, and wanted to keep that concept with me.
