Since Philadelphia's World Heritage City designation was announced within days of the news that the Pep Boys automotive-store empire had been sold to a Japanese conglomerate for $835 million, I wonder if that means Manny, Moe, and Jack are now icons subject to historic preservation?

The Pep Boys - caricatures of three of the company's four founders, Manny Rosenfeld, Moe Strauss, and Graham "Jack" Jackson - have been the advertising face of the business since the first store opened in West Philadelphia.
