Exciting New Children's Book On The Way

[brtmchl]

    My wife has been telling me that my cover art should be something that I have drawn. So I would love opinions as to whether I should leave the cover the way it is, use this, or convert the new drawing into sepia. While I am making changes, I have been thinking of updating the book with a few suggestions that Eva kindly gave me months ago. I want to add a review test in the back of the book and a few maps of Washington, Ford's Theatre, and the escape route. I know there are authors and bloggers who have done so and I am wondering how they went about getting the rights to use them. I would appreciate any feedback. I value the opinions on this site very highly.
