The picture book format is used well, with colorful page spreads showing Gibson in action. I wondered if women tennis players would have worn shorts in the late 1940s and early 1950s, but an online search did turn up lots of picture of Gibson in shorts. I'm always a big fan of photographs (when they exist) in biographies, but younger readers will just pull out there phones and search for them if they want!
There's an afterword providing additional information, as well as a timeline which is very helpful. A short bibliography is included as well. This book is an excellent introduction to lots of different topics for young readers.
