E.T. art

Spielberg's E.T. was on tv this afternoon, so here's a few related art images:

from Stencil Revolution

UFOs in ancient/historic art via Nibiru, Planet X who writes, "This painting is called "The Madonna with Saint Giovannino". It was painted in the 15th century by Domenico Ghirlandaio (1449-1494) and hangs as part of the Loeser collection in the Palazzo Vecchio. Above Mary's (left) shoulder is a disk shaped object. Below is a blow up of this section and a man and his dog can clearly be seen looking up at the object." Check their website out - lots of interesting images with UFO/disk-like shapes in art throughout history - taken with a grain of salt of course.
