I'm not remembering the reason or the story behind the above sketch apparently done in 1993, but I do know it's an olive tree.
Since I was a girl, twisted, gnarled trees have been a favorite subject matter in my drawings and paintings. Once I'd spent my entire two week Christmas break in 12th grade sizing up my black ink drawing of a twisted pine and painting it as a mural on my bedroom wall. My mother taught me how to use the grid technique and use blue chalk powder through pin holes to trace the full-sized template onto the nine foot by eleven foot surface, which I then afterward painted in Prussian Blue acrylic paint, mixed with black on an azure blue wall:
Here is the original ink drawing of the tree I painted on my bedroom wall as a teenager. The grid ratio is 6 inches to the half inch square. Needless to say, I was grief-stricken when a couple years later theysold the house. I was told the mural was a selling point, but I did not profit from it.
