Ema Gordon Klabin Cultural Foundation

This guide to the Ema Gordon Klabin Cultural Foundation in São Paulo turns on two painted parchments hanging side by side in the house's bedroom, one genuine from 1520 and the other a convincing fake made around 1900 by an unidentified artist known only as the Spanish Forger. His technique fooled dealers and museums for decades, including a director of New York's Morgan Library. Look closely at the gold leaf and faces on both pages before deciding which is which.
