The arms of U.S. President John F. KennedyThe gold helmets are a variant of the three silver helmets of an ancient Kennedy coat. The border of the shield was added as a further difference. The olive branches and sheaf of arrows are derived from those of the Great Seal of the United States. The mantling is blazoned as argent and gules; this is exceptional to the rule that the principal tinctures of the arms (in this case, or and sable) be repeated. No motto was included in the grant. The diagonal orientation of the shield is called couché and is optional in all depictions of arms.
