Happy first day of fall! In celebration of the occasion, check out this postcard from around 1915. The message on the back reads: “We need you on Rally Day. Remember the date: October 29. Do not disappoint. Help us make this our best Rally Day. Cordially yours, Grace W. Cobb”. The postcard was not mailed, and the text was pre-printed, except for the date and the signature, which were written in.
