Detail of the Day 1945 Coca-Cola Recgonition Cards

This one needs some clarification. It's from a 1945 WW2 ad. It shows some interesting items. At the wall there is one of the "careless talk" posters and two Coca-Cola allied airplanes posters. Playing the cards, from the left we have a Canadian army sergeant, a sailor, an army corporal translator (T) or technician. If he is a technician, may be one of the Coca-Cola technicians on the front that operated the small Coca-Cola portable combat plants. Then there is a British airmen (probably not a pilot because the ranks of the other at the room) and a first class sailor. They are playing with a Airplane Recognition Card Deck distributed by thousands everywhere for the allied soldiers. During the war some 5 to 10 different decks with actualized combat airplanes, both allied and enemy were issued by Coca-Cola.
