This 1950s bank envelope from the Salem Co-Operative Bank features advertising from several businesses in Windham. Included are ads for businesses of well-known men in town, including Armstrong, Brown, and Butterfield. The only business with a Windham exchange telephone number was Brown & Sons, with a telephone number of 582-W3. All the other Windham businesses featured on the envelope use Salem exchange telephone numbers, even the Butterfield Insurance Agency located on Golden Brook Road. The first telephone in Windham was installed at the turn of the 20th century by George Clark, who ran a telephone line from Hudson to his store on Mammoth Road. Not long after Clark installed his telephone, William H. Anderson had a telephone installed at his gristmill in West Windham. Shortly thereafter, telephone lines began to spread throughout Windham; different regions of Windham were serviced by the exchanges of four different towns: Nashua, Derry, Salem, and Pelham. The use of the various exchanges began to fade out by the 1960s and 1970s.
