My dad is a big garage-saler/antiquer/&c, so he sometimes picks up cool stuff for me instead of things to resell. Or I claim them before he can post them to ebay. Either way, I end up with some pretty awesome stuff.
His latest find is this adorable card catalog, made by Globe and with a patent of 1900. It's over a hundred years old, but has held up pretty well! All the drawers were present, and all but one still had the locking filing system inside. And he got it for only 4$. :D
