"I am very proud today to buy the first of the new $75 denomination United States savings bonds, a bond which bears the portrait of our late, beloved, and brave President John F. Kennedy."
"Buying bonds for our Nation's security is a sure way to express such confidence and I take pride and pleasure in presenting my check for the first $75 bond to the Secretary of the Treasury, Mr. Dillon..."
"Our responsibility to our country, as President John Kennedy said, 'is not discharged by an announcement of virtuous ends.'"
"I hope that many of my fellow citizens will follow this example."
