Here are two new covers for this title. The non-series editions were published between 1903 and 1908. 1909 and later editions were part of the Jester Life Series (#112).
The suede covered book was published throughout those years. It appears that the half vellum book cover was the later of the two cloth formats. It is unclear when the switch was made.

Dust jackets that match both covers have been seen on post 1908 Jester Life Series books. Thus, the jackets are not necessarily a good book dating tool.
