Woman in Blue with a Beret on Self- portrait with a Palette of 1906. With 50% of control over transparency, we notice the following similarities in the invisible:

• The oval shape of the face in Self- portrait with a Palette of 1906 coincides with the one of Woman in Blue with a Beret as well as Celestina but the self- portrait is wider.
   
• The nose is drawn by a line that starts at the root of the eyebrow until the base of the nose.
   
• The nose is Picasso’s and they are identical.
   
• We can find the sinuous line at the height of the eyebrow marking the eyelid as well as the line marking a circle under the eye.
   
• The almond shaped form of the eye.
   
• The sinuous line at the root of the nose with two loops rounded on either side.
   
• The rather long wrinkles under the nose, starting from the root of the nose until the upper lip.
   
• The axial line of the mouth with the lips are identical and are Picasso’s.

It seems that Woman in Blue with a Beret reflects Picasso who represents himself under the traits of a prostitute because he loved to disguise himself. At the source, it is always his own features. The difference lies in the look. Picasso’s eyes are « Spanish eyes » with a black pupil drawn in the iris. The eyes of Woman in Blue with a Beret have a pale iris and a pupil well marked with a white reflection.
