I need to figure out a way to decorate a broom to represent a historical event, anyone have any ideas?

This is for Harry Potter night at a bookstore, the kids are supposed to be able to do kind of a scavanger hunt, identifying what ociate has which broom. The only suggestion anyone has had for me has been the Salem Witch Trials, which is not kid friendly. One coworker is doing the moon landings by putting dixie cups over bristles painted red; another is doing the sinking of the Titanic (way too morbid, in my opinion) by making his an oar. My only idea has been the founding of Athens, by making a trident being choked by an olive branch - which is way too esoteric, and obscure. I'm at a complete loss, and have less than 12 hours to figure it out.
