Thought I'd share this. It is the PRO sign from my fathers station in central MN where I grew up and spent most of my youth. Not worth much, but more of a keepsake. He sold out years ago and has been in the attic since the early/mid 80's so I figured it was time to move it before someone else did... I don't think they had any branding of oil or maps that I can remember, just the sign. Anyone know or have any Info or thoughts on PRO?.
(The PRO station was converted to SuperAmerica, hence my username - I collect SA stuff also)
