The guy in the picture to the left is Damon Runyon. He is one of my favourite authors. If you have never read him, give him a try.
Quite by chance today I came across a site with freely downloadable sound files of many (if not all) the episodes of the Damon Runyon Theater, which was syndicated to local radio stations in the USA in 1947 and 1948. Even if Runyon’s style and subject matter are not to your taste, you may be interested in the hours of recordings of now outdated American accents, many of them from New York and environs.
