Michelangelo Up for Grabs: A chalk-and-ink drawing by famed artist Michelangelo not seen in public since 1836 will be auctioned in London July 6. “We haven’t put an estimate on it because there is no previous yardstick for a drawing of this importance,” said Susan Adams, spokeswoman for Christie’s auction house. The drawing, from an undisclosed private British collection, depicts the holy family fleeing into Egypt.
