A Map and a Mule is the story of Queen Isabel of Portugal, a workaholic peacemaker of the late 13th and early 14th Centuries who prevented several battles, including one between her husband and their son (ah, the Middle Ages!). For ages 5 to 8 with plenty of illustrations, including a vintage map and the cover watercolor. The picture here is a link to its Amazon listing.
And this is the entire interior:

From a reviewer:
” . . . most important is the idea of seeking peaceful solutions to disagreements. A Map and a Mule is a great little book with a great big message” – Wayne S.
