Object No. 79 of 100

[The auction for this Significant Object, with story by Naomi Novik, has ended. Original price: $3. Final price: $31. ]

Found at the base of a street lamp near Madison Square Park, beneath a rain-bleached photocopy with a picture of the same object, in black and white halftones but recognizable. Beneath the picture it said IF Found PLEASE RETURN. The bottom edge of the poster was ragged where all the small strips with phone numbers had been torn away, and the strip of tape holding it to the pole was peeling up from the corners.
