ABSTRACT:
A mailbox accessory for indicating mail delivery frictionally grips the entry flap on a mail box of the type having a downwardly tilted entry flap for opening the box to receive mail. The accessory provides bistable positions for a mail delivery flag when the mail box flap is closed, one such position set by the box user when closing the flap after picking up mail cocks the flag into an uppermost position and the other such position pivots the flag into a lowermost position when the entry flap is opened to remove delivered mail.
