During a renovation of a Mexican Restaurant the new owner gave me a painting left by the previous occupants and I can't find its identity! It says in the lower right corner it is part of the Marina Picasso Collection. It is a woman with a blue face and the date 15-5-63 across the middle of the painting. I don't know how to post a picture here but will email you a picture if you would take the time to help me! I love this painting and would like to find out its history-if it has one! Thanks!
