Never figured signs would bee that much of a draw, since there was countless ones made, based on how much money a store or company had. I have a few that i've picked up with my secondary job.. Two are advertising signs far I got cleaning out a workspace, but the rest (save for one!) are from worksites...
The two signal pics are related to my second job, they are supposed to be connected up to an intersection controller, but it's back at the manufacturer getting a part repaired.
