A while back I featured a W. W. Denslow cover for a book published by Rand McNally called The Fifth of November. I've recently picked up a second copy of this book. This one is a different binding state, as Denslow's seahorse signature is not on the cover. It can be seen on my first copy, (shown above on the right) on the left of the barrel design. I'm surprised by how many of these books seem to have removed Denslow's logo on later bindings/printings - I don't really understand why they would go to the bother.
This later binding is also of a lighter cloth color than the original. The stamping is in brown rather than a deep purple/red, and a small illustration of the headsman's mask and ax has been deleted from the back cover.
The original poster for this book, which I'm showing on the right, is in the collection of the New York Public Library and can be seen online in their digital collection. It's interesting to compare the differences between the poster and the book cover. The book very successfully combines the main elements of the poster into a single simple image.
