A poster hangs on the wall of Richard Idstein’s home on this quiet street in a northwest Chicago suburb. It says Bataille Des Ardennes in bold black letters with the years 1944 and 1994 below it. In the hallway, near the front door, is a picture frame holding a Purple Heart, bullet and Army medals. It’s the home of a World War II Soldier who remembers the day the Battle of the Bulge started.
