To be filed in Artifact Storage upon the restoration of the world:

A rectangle of dark grey cardstock bearing a watercolor sketch of a green lamp, a small moth, and a half-spider/half-human figure standing on a web watching the moth through binoculars. The card is captioned “Looking forward to seeing you here!” in red; instead of a signature there is a drawing of a candy cane and a modified ::::) emoji. The card was recently discovered in Martin Blackwood’s back pocket.
