You might expect "F is for Fireworks" and "M is for Mount Rushmore" in a fun alphabet primer for prereaders, but for kids who are ready for more advanced concepts, the depictions here also include Washington crossing the Delaware, Ben Franklin unfurling the Declaration of Independence, and Francis Scott Key writing the national anthem. Lighthearted and mid-20th-century retro, Greg Paprocki's illustrations contain many details that viewers will appreciate only upon subsequent viewings of the book.
