An extremely rare oversized broadside poster (measuring 18.5x6.75"), this also served as the racing program for August 6, 1878, and was issued by the official printer of Saratoga track programs for several years. Broadsides were large sheets of paper that were printed on only one side. Historically, they were used to announce upcoming events informing the public (this included early printings of the Declaration of Independence!). An extremely rare and unique piece even for this era, as these type editions were not commonly done.
