Wallet Card at the Fourth Avenue Building

Manhattan has First Avenue, Second Avenue, Third Avenue, Fifth Avenue, Sixth Avenue, etc...but no Fourth Avenue. There used to be a Fourth Avenue, but most of it was renamed Park Avenue around the turn of the 20th Century, and in 1959 the last stretch of Fourth Avenue became Park Avenue South. However, 381 Park Avenue South still retains its old name, the Fourth Avenue Building, on a sign at the top of the building.
