This week’s Vintage Vinyl video comes to us from the Baltimore suburb of Eldersberg, Maryland, where Shannon-Baum Signs & Graphics operates its full-service sign, graphics and wrap shop, which started in Baltimore way back in 1950. Here, we watch as a team member does a custom install on a mailbox. We’re pretty sure the mail carrier doesn’t mind being greeted by the dog every day, given that it’s a Golden Retriever.
