I just found this site,,,very cool. I used to have a collection of catalogs from about 1978 and up. Tossed them a few years ago...shouldn't have. That was like a whole culture...my dad used to go every fall and get me a catalog, like clockwork. Having the catalog was as good as getting something from the store.
I later worked in the same store when I graduated high school and was starting college.
Anyway...I have the old translucent sign screen from the store in our city that was there, as far as I know from about 78ish until about 1992 or 93 in a remodel.
They are about 10 feet long by 4 or so feet high...2 of them. Kind of heavy if I recall.
It says RADIO SHACK...and has "Plus Computer Center" on one corner. Been in my barn since 93.
I would take offers...pickup only, I'm in Southern Ohio.
