This item from the papers of Carl Julius Adolph "Ado" Hunnius is an invitation to the 33 year reunion for the 54th Regiment, New York Volunteers, which was held in the Victor Ecstein Metropoliten Hotel in New York City, New York. Hunnius joined the 54th New York, which was composed largely of German immigrants, during the American Civil War to serve the country in which he spent the rest of his life. After the Civil War, Hunnius moved to Kansas and served under Major General Winfield Scott Hancock during the 1867 effort to pacify various Native American tribes on the Great Plains.
