The cover for the book "The sailor on horseback" describing Jack London's life written by Irving Stone was designed so that you can see two appropriate pictures. The picture you see below is a sketch of how it was planned.

To create a sailor on horseback I needed this picture, added to it some waves and then the sailor itself

 

 

And our first cover

Our plan was to have both Jack London's picture and the image of sailor at the same time but separately (idea seen on the sketch also).

So we took the picture above and added some styling for our book.

And the second cover above the first one :)

which could be glued

or can be wrapped
