The door knocker is a symbol of hospitality and welcome - especially in the hotel industry. It is also the perfect way to recognize that tenacious, determined sales person who goes out day after day knocking on doors (literally or figuratively) to drum up sales. This two part door knocker lapel pin actually works. The knocker swings on a hinge. Measures approx 1" X 5/8". Gold finish. Military clutch back. Proudly Made in USA
