This is a Neckerchief/Dickie which once belonged to Obergefreiter Erich Radtke, an NCO aboard the German Panzerschiff (Pocket battleship) Admiral Graf Spee, injured during the Battle of The River Platte in Dec. 1939. He and the remaining crew spent the rest of WWII as "guests" of the Argentine government before returning to Germany in 1946. He survived the war and died in Germany in 1970. I got this on ebay recently when the owner of a huge collection of Graf Spee items auctioned some of them off. I don't normally buy German items to keep anymore, but this piece of WWII history was too much to resist and it was relatively inexpensive. I have chatted by email a bit with the man who sold it to me and he told me that Radtke sent him many items from Germany because his grandmother was Radtke's girlfriend during the war. I am also posting a picture of the section of the crew list with Radke's name on it.
