  The governor of this state is authorized and requested to issue annually a proclamation calling upon our state officials to display the American flag on all state and school buildings, and the people of the state to display the flag at their homes, lodges, churches, and places of business, on the second Sunday in May, known as Mother’s Day, and on the third Sunday in June, known as Father’s Day, as a public expression of reverence for the homes of our state, and to urge the celebration of Mother’s Day and Father’s Day in the proclamation in such a way as will deepen home ties, and inspire better homes and closer union between the commonwealth, its homes, and their children.
