Digital advertising on Grand Avenue

Speaking of street advertising (we were in the Big Belly story), you may have noticed that the Van Wager digital sign has been gone for months. That big light up sign that was next to the bus bench. There was an issue over the sign at the bus stop on Grand Avenue near Virginia Street. There was a static bus sign there for years and then the new glow-in-the-dark digital sign was put in. But after many complaints it was removed.

It was quite a mess and a lot of wasted money as the city dug up the street and spent a week working on the wiring. Which brings up this issue: Mayfair is installing a big tv-type thing over one of the entrances to their offices. It's at the entrance to where the old Antiques Market was; at the former Benetton store. Is this ok? Since it is part of the building is it ok on the historic street? The bus signs were not because of the street's historic status.
