A nice touch is the illustrated spine that looks good on a shelf.
Navaho Weaving by Charles A Amsden HC 1949 Complete Fold Out
The entire book is illustrated in a watercolor style that feels soft.
The illustrated glossary at the back is both helpful and pretty.
What stands out about this history book is the illustrated battle maps.
Reading this novel is like watching a painting come to life.
What I like is that the book is illustrated without overwhelming the text.
