What is a BUSYBODY, you may ask. As any resident of Old Philadelphia can tell you, the BUSYBODY is a set of three mirrors set in a black metal frame - two mirrors on the bottom and one mirror on top. It is held together by a scrolled iron bar which mounts alongside or under a window, or next to a door, usually on the second or third story of a house (first floor for ranch type houses).
By adjusting the mirrors, the home dweller can see who's at the door below, or what's going on up and down the street
Invented by none other than Philadelphia's most famous denizen, Ben Franklin!
Attaches to windowsill with 2 screws. Overall height 21". Overall width 12 1/2". Each mirror measures 5" x 6". Sources: Busybody1 Busybody2
