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 various novels, but it is a mystery to me which novels they actually come from. If anyone knows then please feel free to leave a comment!
