Decided to frame some issues to display, what do you think of my choices?

This is just a mockup.

Some of the choices are obvious, others are sentimental, had since I was a kid.

I have collected all but two, and haven't bought frames yet. I found some that are cheap but not the best... if anyone has a recommendation for 15 cheap frame that be great!
