“The Berlin Wall (German: Berliner Mauer) was a barrier constructed by the German Democratic Republic (GDR, East Germany) starting on 13 August 1961, that completely cut off West Berlin from surrounding East Germany and from East Berlin. The barrier included guard towers placed along large concrete walls, which circumscribed a wide area (later known as the “death strip”) that contained anti-vehicle trenches, “fakir beds” and other defenses. The Soviet-dominated Eastern Bloc officially claimed that the wall was erected to protect its population from fascist elements conspiring to prevent the “will of the people” in building a socialist state in East Germany. However, in practice, the Wall served to prevent the massive emigration and defection that marked Germany and the communist Eastern Bloc during the post-World War II period”. – Wikipedia

“G.I. Joe is a line of action figures produced by the toy company Hasbro. The term G.I. stands, in popular usage, for Government Issued and after the First World War became a generic term for U.S. soldiers. The origin of the term dates to World War I, when much of the equipment issued to U.S. soldiers was stamped “G.I.”, meaning that it was made from galvanized iron. The development of G.I. Joe led to the coining of the term “action figure”. G.I. Joe's appeal to children has made it an American icon among toys”. – Wikipedia. Photo: Vintage G.I. Joe figurers are on display at the 2003 Hasbro International G.I. Joe Collectors' Convention June 27, 2003 in Burlingame, California. (Photo by Justin Sullivan/Getty Images)
