Cartoon
This term has two quite different meanings: a) Initially, refers to a detailed preparatory project on cardboard on a table of painting, a fresco or even a shield. Wonderful are the drafts of this type of Raphael (for a series of panels that were originally destined for the Sistine Chapel, and now are found in the Vatican Palace), as well as the painting of Leonardo, with the title “The Virgin and Child with Saint Anne”. B) Nowadays is, generally, a satirical sketch with specific, usually political, edge.
