ABSTRACT:
A signal device for attachment to a rural-type mailbox provides a visual indication to a remotely located observer that the box has been opened for insertion of mail. The signal device comprises an elongated, flat, flexible arm including means at one end for adhesively attaching the art to the inner surface of the hinged door of the mailbox, and a brightly colored signal flag at its free end. The configuration of the adhesive juncture of the arm with the lid is such as to facilitate flexing of the arm with minimum stress upon the adhesive layers, whereby the arm can be manually bent over and inserted into the mailbox upon closing of the lid. When the lid is subsequently opened and closed for mail delivery, the arm assumes its normal, erect position with the signal flag displayed outside the box.
