War Bonds take them up!

88 War Bonds take them up! Only the highly trained, courageous pilots of our R.A.F. can take up the Spitfires and the Hurricanes. But you, the citizens of Britain, can provide the planes—and the ships and the weapons—with which the Battle of Britain will be won. You can take up National War Bonds. Vast sums of money must be forthcoming at once to ensure victory. National War Bonds provide the opportunity for great firms and small firms, executors and trustees, and individual investors to put their financial weight solidly into the balance against the danger that threatens us all.
