I've been looking at Sorolla's apunte's lately. That's the word used in a book I have for his small, quick oil sketches he made on sight. The english translation is simply note. And that's what they are, quick notes of a scene. I'll put some up on a later post, but not here with mine!
This is a quick apunte I did in downtown Phoenix. The Westward Ho, Fillmore and Central.
