Well, who's to say the others were accurate either, but it's not the first time movies and/or TV shows have had detailed signs for taverns/inns that are supposedly located in 18th century (or even 17th century) backwoods New England locations. Apparently there were talented graphic designers in every NE village.
I love the Hallowell University logo. I have to confess I never even took note of it when I saw the pilot. But then, I was paying attention to the performances and not the clothes. However, if the pilot is ever shown again, it could be fun to try to spot the sweatshirt.
Thanks for alerting us to the site, Housefly.
