Georges Topfer was a French spanking artist from the late 1910s to the mid-1930s. Topfer often used the pseudonyms Gaston Smit, G. Smit, GTS and James Barclay. Below are his illustrations from the 1933 novel Petite Dactylo (Little Typist) by Sadie Blackeyes.
No new work of Topfer is known to have appeared after 1933, making these illustrations some of the last he is known to have produced. Although the novel has 32 illustrations by Topfer (I was not able to locate all of them), the frontispiece is done by the artist Louis Malteste.
Update: I was able to find more illustrations in The Art of Discipline Volume Two: A Pictorial History of the Smacked Bottom. Originally the illustrations were overlooked because in the book they are listed under “G. Smid.” It is my belief that they are done by Topfer, who often went by G. Smit, so I’ve included them as well.
