this painting was done in the 1990's. See how the Twin Towers have been hit, and even what could be Tower 7 (which also mysteriously came down) : Boris Vallejo's Site
off on a tangent a bit, here are some other 9/11 premonitions in art. the most freaky of which isn't on that page, it was done by Alex Grey (the guy who does some of Tool's artwork). About halfway through this vid Alex shows us the painting with the premonition : *"Premonition" may be defined to include ordinary predictions, a fallacy of linguistic ambiguity can lead to an overly supernatural explanation for predictions' accuracy. they're just intelligent / coincidental predictions - there's no such thing as the supernatural.
