Courtney Hodges as a pinup?

Why would anyone go through and cut out the headshots of historic figures in Charles MacDonald's The Last Offensive (Part of the official history of the U.S. Army in WWII)? From a library book, no less?

An illustrated book report? Or is some kid's bedroom plastered with grainy images of famous (and not-so-famous) generals of WWII?

(The book was also de-mapped, which is annoying as well.)
