Earlier this month I created the following "book trailers" for an online Materials for Tweens class offered through San Jose State University. Searching for copyright-free photos and audio wasn't easy. You win, public domain.
First up, a promo for Twelve Rounds to Glory: The Story of Muhammad Ali by Charles R. Smith Jr. and illustrator Bryan Collier (2007).
Next, John Lennon's print debut, In His Own Write (1964).
