Back when the Second World War broke out, the matchbook industry landed its biggest client - the United States Government.
There was a sudden need for patriotic and military advertising. Matchbook's industry asked the public to support the war-effort and to buy war bonds, asked people to boycott German-made goods and so on.....
Naval bases ,forts ,air fields,even U.S. warships had their own matchbooks.Overseas soldiers were given matches as part of their K-Rations that proclaimed, "I'm Proud Of You and So Are The Folks At Home."
By the end of 1945, over 200 billion matchbooks had been printed.
