This was in "Outdoor World and Recreation" in 1913

The other variant is more simple, and this one carries the signature "Kemble".
I couldn't confirm, but it is likely that of E.W. Kemble (1881-1933) who was chosen by Mark Twain to do the original illustrations for the first edition of "Huckleberry Finn" in 1884 when he was only 23 years old. He also did a later edition of "Uncle Tom's Cabin".
