In addition to the black-and-white drawings by Rene Bull, there is a color frontispiece by Harry Rountree. At a rare books site, I also found some additional Rountree illustrations (my personal copy has only one colored plate by Rountree).
You can see the stories with illustrations by Bull and by Rountree.
