The broadside poster was once the staple of railroad special trip advertising.   Here we find one from the Rochester & Genesee Valley Railroad Museum’s archives advertising a May-Day trip from Rochester, NY to New York City for “Only $7.00 Round Trip!”   It helps that this poster is for May 2, 1899, and to get this price, you need to return before May 7, 1899.  Departures were 6AM or 5PM from Rochester, and you needed to see the Passenger Agent if you wanted to make Pullman accommodations.   Jump ahead 111 years, the cost as of November 23, 2010 for a coach round-trip ticket for May 2, 2011 on Amtrak is…  $114.00.
