Joaquín Sorolla did not like to sign his work. A large portion of his work does not have a signature, and it is barely visible in his signed works. Up to five distinct hands have been found to have written Sorolla's signatures; when he needed to exhibit a large quantity of paintings, Sorolla would ask his wife and children to sign them.
Sorolla's preferred place to sign was in the lower right corner, although some signatures appear on the lower left and another appears camouflaged between the brushstrokes of the work.
In Sorolla, we find neat, careful handwriting that is tilted to the right. Sorolla's lines indicate that he didn't want to stand out; rather, he wanted to be himself, a person of great simplicity and humility at peace with what life gave him.
His handwriting demonstrates a personality brimming with life and vibrancy in a personal environment where painting consumed his existence - painting and his family.
