michelangelo sistine chapel study christies 2718805

A previously unknown Michelangelo drawing, a red chalk study for the foot of the Libyan Sibyl on the Sistine Chapel ceiling, was discovered after an owner submitted a photograph to Christie's online estimate service. The work, created around 1511–12, sold at Christie's New York for $27.2 million, far exceeding its $1.5–2 million estimate and setting a new auction record for a Michelangelo drawing. The anonymous seller inherited the piece from his grandmother, and it had been in his family since the late 1700s.
