Cartoon in 'Punch' magazine entitled 'Discipline'. The blackboard reads 'France ought to have Alsace-Lorraine Carl' referring to the German suspicions that in March 1917 a secret message was sent from Emperor Karl I of Austria via Prince Sixte de Bourbon to French President Poincar? promising support for the French claims to Alsace-Lorraine. This message was published by the French government in April 1918. In the cartoon, Carl Hapsburg exclaims "Please, Sir, I didn't write it" and Dr. Hohenzollern retorts, "For the credit of the school I shall publicly accept your denial. All the same, my boy, you will now step into my private room".
