Diptych of Federico da Montefeltro and Battista Sforza

The Diptych of Federico da Montefeltro and Battista Sforza are two oil paintings by Italian artist Piero della Francesca, dated to 1473–1475. This famed double portrait is often mistitled The Duke and Duchess of Urbino—as it appears on the website of the Uffizi Gallery, which owns it. Since Battista Sforza died in 1472 and Federico da Montefeltro was not made duke until 1474, Battista never attained the title of duchess.
