This privately printed post card (Paid Koch G.M.B.H., Aschersleben) with a favor cancellation dated 23 May 1937, commemorates the 43rd German Philatelic Day, 22—23 May in Kassel. The event was sponsored by the Reichsbund der Philatelisten. Depicted is the Schloss Wilhelmshohe and the colossal statue of Hercules which also appears in the commemorative cancellation.
Schloss Wilhelmshohe, formerly the summer resident of the Electors of Hesse, is a freestone building in the classical style. It was erected in 1786-1801. The interior is in the style of the Empire and contains souvenirs of Napoleon III, who lived here as a prisoner of war in 1870-71. The Octagon, 1360 feet above the River Fulda, is an artificial ruin built in 1708-11 consisting of three vaulted stories. The platform, which commands a beautiful panorama, bears an obelisk, 98 feet in height, surmounted by the statue of Hercules. The statue, in copper, is itself 30 feet in height. The Grotto in front of the Octagon contains surprise waterworks.
