In July 1997, a commercial on WEW began, "Are your current ways for attracting business not working? Perhaps you should consider one of the most effective forms of visual advertising--signs."
The announcer then touted the benefits of having Signarama create signs for one's business. Hearing that ad on tape recently made me think, "Have I heard any commercials for sign-making businesses since then? I'm not sure I have."
Sign-making is an obvious idea for a business. Ironically, though, it's one of the least-advertised ones I've ever heard.
