picasso's erotic code

picasso's erotic code:

Picasso's Russian wife, Olga, a former ballerina and the mother of their son, Paulo, had begun to suffer from a nervous disorder that her pathological jealousy, resulting from her husband's nonstop infidelities, made infinitely worse. Picasso would have to keep Marie-Thérèse hidden. Since Olga was always on the lookout, Marie-Thérèse's first appearances in his work are in somewhat erotic code: as a guitar waiting to be played, as the boomerang-shaped collar and cuffs she bought the day they met, and as her initials, bifurcated by his. Picasso was more in love than he had ever been.

I'm finding as I get older Vanity Fair is becoming a much better read. Could just be me.
