Two flags with a three-leaf clover below black text over white background. Olive green ribbon hangs below connected to two lucky rabbits' feet, one green and one brown.
During the 1850s, the potato famine caused many Irish to immigrate to the United States. The Irish phrase "Erin Go Bragh" means Ireland forever. The phrase is often used to express pride for and allegiance to Ireland. The shamrock and the green harp flag are also symbols of Irish identity and nationalism.
The rabbit foot, like the ones attached to this button, is considered to be a good luck charm.
