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

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

La Joconde nue:

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):

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

Why are you a Muslim? Why is it Islam for you and not something else?

Another version of the above exists, attributed to Salaj:

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

While overall similar, there are differences in the shape of the face, the background and other details.

Donna Nuda:

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.

I’m wondering about attachment and transference with the therapist and the idea of escape and fantasy? How much do you think your strong feelings, constant thoughts, desires to be with your therapist are a way to escape from your present life? I wonder if the transference serves another purpose than to show us our wounds and/or past experiences, but is a present coping strategy for managing what we don’t want to face (even if unconsciously) in the present—-current relationships, life circumstances, etc. Can anyone relate to this concept of escape in relation to their therapy relationship? How does this play out for you?
