A bilingual life of the great Mexican muralist Diego Rivera, weighted toward his early life (he was a poor scholar whose sympathetic parents provided plenty of artistic materials and sent him to art school quite young) and his pride in his heritage. Winter's small, bordered paintings, in rich, intense colors, nicely evoke folk motifs and other themes in Rivera's work, including his concern for ``poor people'' and their ``war for equality.'' An excellent beginning biography. (Biography/Picture book. 6-10)
