This bust of the Emperor Hadrian dated as contemporary to his reign (mid second century AD) just sold recently at the Sarrou and Associates auction in Paris,















This "selfie" snapshot taken by Andy Warhol just sold at a Sotheby's auction in New York.




















One of these sold for 1.5 million dollars.  The other sold for 30 million dollars.

Guess which is which?

Hint:
Hadrian ruled over the world's most enduring empire at the absolute apex of its power.  He was a great aficionado and collector of Greek art, and he employed the greatest Greek artists of the era, one of whom certainly sculpted the masterpiece above.

Warlhol took lots of neat photos of the biggest pop celebrities of the 1960's - himself included!  And he also had the "concept" to take "ironic" photographs of pop icons like soup cans and cereal boxes.
