Mr. Potts shares many traits with Abraham Lincoln and helps his young neighbor learn all sorts of interesting things about Lincoln's life before and after becoming president.

This focuses on Lincoln's youth of labor & determination, and his ethics, and so avoids the more controversial bits.  It's probably a bit too laudatory, but we need heroes who are good role models and I say this is fine.  The conceit makes the book very engaging, even though it's for schoolchildren (too long for under 6).
