ABSTRACT:
A mailbox signaling device comprises a pivotal plate on the base of a mailbox which is raised from a prominently exposed position below the box to a substantially invisible position flush with the base of the mailbox when mail is delivered into the box. Accordingly, the plate may give the impression when it is exposed that it is in a signaling position, although the box is actually empty, and when mail is delivered, the plate is invisible and no signal is therefore evident, except to persons familiar with the workings of the device, that mail has been delivered into the box.
