This one dates back to October 9, 1924 in LIFE magazine. It shows a little bit of water damage, but the piece has been treated to stop any further discoloring and deterioration. It measures 20 X 14".
I don't know of any other illustrator/cartoonist who depicts a bear this way, weighty on top and thin around the bottom. It is usually the other way around (Yogi Bear, Baloo etc.) Beautifully designed human characters, and the hounds are priceless.
