Some of us like to collect cars and others like to collect stamps. And if you like both you are probably ecstatic over the United States Postal Service recognizing muscle cars and Mecum’s venerated Indy Auction with commemorative stamps. Mecum’s annual Spring Indianapolis Auction has been recognized around the world as not only the original muscle car auction but one of the largest. This year will be Dana Mecum’s 26th Original Spring Classic and with the emphasis on muscle cars is the perfect place for the U.S. Postal Service to highlight its five new limited edition stamps featuring iconic muscle cars. The stamps will be featured on display and be available for purchase during the Indianapolis auction which runs now through Sunday, May 19th.
