Jehan Rictus (1921) (Private collection, U.S.)
In this etching, Steinlen has added several etching technique tips. In the right margin, he has written "pointes diverse" (various points), "pointe fine bois" (fine point wood), and "diamant" (diamond) beneath lines made by the referenced tools.
Compare this to the similar 1914 etching. http://www.steinlen.net/main.php?g2_itemId=37
