Blues Brothers Detective Badges Props - From the original Belushi/Aykroyd mega-feature "The Blues Brothers" (1980) comes these two Wm. J. Burns International Detective Agency Guard Badges. `The use of this real Detective Agency which closed in 1932 was an in-joke being that William J. Burns (who started as director of the BOI, a predecessor of the FBI) was notorious as a union buster, and basically a man who with his organization would allegedly take money to track down anyone, or cause any kind of trouble you wanted. The two metal Detective Agency badges are approx. 2 1/2" x 2 1/2".
