Did Leonardo da Vinci paint two Mona Lisas? Where are they?

There is only one Mona Lisa, at the Louvre, fully credited to Leonardo. However, there are several Mona Lisa look-alikes from his studio, some of them quite saucy. The one most similar to the Louvre one is the Prado Mona Lisa, a copy made simultaneously in Leonardo's workshop while he painted the Mona Lisa, probably made by an apprentice(s):

Then there are the ‘meza nuda’ paintings from his workshop, often referred to as Monna Vannas.

Evidently there was a market for erotic paintings. The American art historian David Brown, curator of Italian Renaissance paintings at the National Gallery of Art in Washington, has suggested that da Vinci painted a saucy parody of the Mona Lisa for his patron Giuliano de Medici, and that the Salai version is a copy.

For the one below, art experts suggest that it contains touches indicating that Leonardo contributed to it.

Obviously, the original Mona Lisa also inspired some cheeky versions of her.
