Envelope addressed to “Mr. Joseph H. Sears, East Dennis, Mass.”; the return address is “Chas. E. Southcod, Room 5, First National Bank Building, Greeley, Colorado.”; the postmark is “Greeley, Colo; Sep 23; 1940; 1230 PM.”; on the envelope, on both sides, is a list roughed out, which is apparently a response to a questionnaire concerning the estate of Joseph Sears’ relatives in Greeley.
