Folsom Prison opened in 1880. Eighty-eight years later, Johnny Cash recorded "Folsom Prison Blues," and an album's worth of other hits, live for its inmates. And this padlock is all that separated Cash from his audience of max security California State criminals.
Nah. It's just an antique padlock with a Folsom Prison nameplate. Fully functional, the 19th century replica comes with 2 skeleton keys. Use it to lock up your liquor cabinet, your kids' candy 'til they clean their rooms, or your co-worker's laptop 'til he agrees to share some of the chocolate caramel crack brownies his wife made with you.
