Julio Romero de Torres
La Chiquita Piconera by Julio Romero de Torres, Spanish artist (b. 1874 - d. 1930)
This is one of Romero de Torres' most famous paintings and was featured an a 5 peseta Spanish stamp (and often copied.) Julio Romero de Torres was a big deal--he and his art were on the 1950s era 100 peseta bill and there is a popular folk song about him. Unfortunately, there are no books in English on Romero de Torres but you can see more of his work here, here and here.
La Fuensanta (the work featured on the 100 peseta note)
The model in both paintings above is María Teresa López. She began modeling for him as a child and by 14 Julio was obsessed with his "muse". María was bitter about how modeling and being in such famous paintings ruined her life. No one ever believed that she was not the artist's lover. Her first marriage lasted 2 years and ended badly. Her husband tried to prostitue her and when she resisted he beat her. She never remarried. (Story with quotes en español.)
