Poland once gave the United States a birthday gift that was a touching gesture symbolizing the international appreciation of American independence.

Two years ago, the website for the Library of Congress published the entirety of a Polish birthday card that was given to the United States on the 150th anniversary of when America claimed independence. The card includes 111 volumes of well wishes as well as 5.5 million signatures from the Polish people.

The Polish Declarations of Admiration and Friendship was given to President Calvin Coolidge in 1926, and it was also meant to be a thank you from the Polish people who were grateful for American aid during World War I. The 30,000 pages are full of full of color and history, as they include pressed flowers, drawings from famous Polish artists, and notes from religious, social, business, military, and educational institutions.

One sixth of the Polish population at the time signed the card, and it took eight months to create it.

“Noble Americans, your national holiday is sacred not for you alone. It finds a warm reverberation over the whole world,” the Polish committee in charge of the project wrote in summary of the message of Declarations. “We, the people of Poland, send to you, citizens of the great American union, fraternal greetings [and] . . . our deepest admiration . . . for the institutions which have been created by you.”

“In them, Liberty, Equality and Justice have found their highest expression and have become the guiding stars for all modern democracies,” they added. “With eternal gratitude in our hearts,” the Poles declared, “we . . . desire . . . to wish your country and your nation all possible prosperity. . . . Long live the United States of America!”
