Long before Twitter and cellphones, there were two-penny postcards: One cent for the postcard and another for the stamp. Folks would mail them out and they would often be delivered the next day. John Cleary will share Winchester’s rich history as revealed by his extensive collection of antique postcards and ephemera, which include views of downtown Winchester, the Fells, and Horn Pond as well as various street scenes. Cleary is scheduled to share his collection with the public at 7:30 p.m. Oct. 17 in the Sanborn House Historical and Cultural Center, 15 High St. Light refreshments will be served beginning at 7 p.m. The Winchester Historical Society Inc. is presenting the program, which is free and also will feature a selection of postcards from the Town Archival Center.
