Decorations... Or Tools?

These guys have been sitting in our bookshelf for a while. A really long while.

Today, I decided to look at them closely for the first time, and I was surprised to find such interesting cameras!

I'm a bit concerned, since I've become increasingly interested in shooting film. I foresee losing money... (Hey, I have to learn anyways so I can introduce the youth group to it, right...?)
