 I have found the holy grail 

Browsing around on the Louisiana state library, and I've come across the holy grail of signs. It's got cutout US routes, cutout diamond Louisiana routes (with a black top, ironically enough), curves and detours, and old fashioned stop signs. Makes me want to jump back in time for a week, steal some, then bring em back.
