Resembles what you/I see after a sign repair. Also, the aftermath of an install by "the professional sign contractor"
We had a rash of neon signage and outline lighting that would magically 'appear' on Monday mornings. IE:
Stop at a conv store for a drink, next store has neon outline ltg, and signage inside of store windows. Wasn't there last week?? No permits issued. Worker said "boss not here";
$ 500 Violation (Fine) to storekeeper. Guy won't give up the installer!
Quite a few 'others'
