A Key Labeled "Do Not Use After Midnight"

A brass key tagged only DO NOT USE AFTER MIDNIGHT, accessioned with no lock and no explanation, which the Museum observes regardless of the absence.

Accession no. NMDP 1949.101

Object: one key, brass, with a fiber tag inked DO NOT USE AFTER MIDNIGHT. Credit line: Collection of the National Museum of the Digestive Past.

Provenance

The key came to the collection in a lot of unrelated municipal hardware, the only labeled piece among them. Nothing accompanied it: no lock, no ledger, no correspondence, no indication of what it opens or of what occurs after midnight if it is used. The Museum has dated the key by its manufacture, roughly 1949, and dates the instruction not at all.

Condition report

The key is unworn; the wards are sharp and the bit shows no rub, consistent with a key that was labeled and then not used, or used only as labeled. The fiber tag is original, the ink iron-gall and legible, the string an ordinary butcher's twine.

Curatorial note

The Museum does not use the key after midnight. It has no lock to try and no hour at which trying would matter, and it observes the instruction regardless, having found no file that would release it from the courtesy. The absence of an explanation is accessioned along with the key, and is the larger of the two objects.
