U.S. 40 is great, wish you were there [Pictures]
Mary L. Martin Postcards — the “world’s largest” postcard collection — fills the back of a Havre de Grace shop and an additional 10,000-square-foot warehouse a few miles north on U.S. 40 in Perryville.
The exact number of cards in the collection is secret, Martin says, but it’s more than a million. And, within that million there are several vintage postcards from tourist spots across U.S. 40.
