I'm convinced that the Coke spotter deck is a reproduction, as in not used during WW2. There's something a little odd about it, in terms of anachronistic information.
The planes on the cards shown are without doubt World War II-era. America might have continued using B-17s for a short while after the war, but I'm pretty certain that the Japanese were no longer using or building Zeroes during the American occupation after the war, just as the Germans (East or West) no longer produced any planes with a swastika on the tail.
The descriptive card that the deck comes with mentions "United Nations and Enemy Aircraft" as well as the position of Aircraft Spotter in "your Civilian Defense Organization." The UN didn't exist during the Second World War, having been formed in 1948. I'm not sure when American CDOs were created, but I'm somewhat sure they're also post-WW2, coinciding with the craze to build bomb shelters for defense against nuclear attack - a weapon used only in the final weeks of the war.
The next major conflict that the US was involved was the Korean War, as part of a larger UN force, in which Japan and Germany didn't participate and Italy only provided hospitals and ambulances for the UN - none of those nation's aircraft would be designated as enemy aircraft. It's unlikely that a current aircraft spotter card deck at any time after WW2 would have any of the enemy planes shown on the cards in your photos.
Mind you, I'm not saying you're doing something fishy - I'm saying that Coca-Cola must have mixed up some of their information when they put this deck together. It can't be an original from the war because of the mention of post-war organizations that previously didn't exist. It's kind of interesting, when you think about it.
