Davanzo was a spanking artist from the period of early 20th century French spanking literature, working for Collection des Orties Blanches. Davanzo could be the same as the artist Wighead, both perhaps being the Italian artist Mario Laboccetta, using the pseudonym Marilac. Below are his illustrations from the 1933 novel Irène et son Esclave (Irene and Her Slave) by Daisy Lennox.
