A package of 5 USPS mail drop boxes, often found on street corners and in front of buildings including banks, municipal offices, and of course, post offices.
Produced in two styles - blue and red for pre-1970's and all blue for later eras.
Minimal prep is required - simply insert a razor knife blade into the space between the legs and twist to remove the small plastic "blob" that protects the legs during production and shipping. A dab of white paint on the front to highlight the pickup time card or represent the USPS logo on the sides.
