The Holley Museum of Military History was not large by any means and it did not have any large scale artifacts like planes or tanks but still had a lot of interesting things. It had a great deal of models of planes and ships, along with propaganda posters and paintings of famous weapons, personalities, and battles.

I was a little surprised at this, they had an entire display case of Bob Dole's militaria from WWII, including uniforms, medals and his dog tags.
