Last month, our readers marched into the online archives of Presidential libraries and marched out with the best photos. We awarded a few t-shirts for the most enjoyable submissions.
We should do that again!
So, anybody have a good suggestion for a topic? The Presidential library hunt worked well because there were multiple places with thousands of public domain images (and the presence of public domain images is the key here). But I'm sure there are better ideas. And if I choose yours, you'll get a free mental_floss t-shirt just for suggesting it.
The floor is yours...
