This postcard was mailed from Duluth on July 24, 1907, and arrived two days later in the mailbox of Mr. A. G. Pack, Jr. of 823 Colorado Ave., Colorado Springs, Colo. It does not necessarily depict a Duluth scene; versions of this postcard exist for Wildwood, N.J.; Atlantic City, N.J. and probably other cities.
