Another Rand McNally title with a W. W. Denslow cover - Margaret Wynne, by Adeline Sergeant, published in 1898. Denslow's trademark seahorse signature can be seen at the lower right, outside the border of the title box. This is a rather worn copy, and the colors appear a bit dull. A fresher copy might be more striking!
Adeline Sergeant also wrote A Valuable Life, which received a much more evocative treatment from Denslow in 1897.
