Pittsburgh and Beyond!
Pennsylvania Rail-Road from Philadelphia to Pittsburgh. Philadelphia: Friend & Aub, 1852.
A bit like today’s pop-up ads, printed circulars brought unsolicited advertisements into nineteenth-century homes and businesses when they were used as stationery. Here, a merchant in Philadelphia used a railroad letter sheet (probably given to him by a railroad agent) to pitch goods to a client in Ohio. An added note mentions the express train from Philadelphia to Pittsburgh that takes “just” 36 hours – today Amtrak traverses that route in 7 hours 23 minutes.
