Frédillo was an artist who created woman spanking art (M/F and F/F) illustrations in the 1920s.
He illustrated works such as La Voluptueuse Souffrance (flagellation passionnelle) by Max des Vignons (1924 edition; this novel was first published in 1908 or 1914 with art from Gaston Noury (most likely). This book was illustrated by various artists ( Jacquette, M. Sc., M.-K., and Gaston Noury). I don’t think it is unlikely that some of these names are the same artist, unfortunetely I have only found art from Gaston Noury to compare.
