I’m not sure how the reporter knew the sign was erected by New Zealanders?
“This is an original press photo. New Zealanders, who probably got their information from a close contest with Nazi Bullets, erected his sign which temporarily halts an American Jeep on famed Highway “6” which leads to Rome. “Achtung” is the German word for “attention” and the warning it headlines is situated a few miles from where the Rapido River crosses the highway south of Cassino. Photo measures 8.25 x 7.25 inches. Photo is dated 3-18-1944.”
