Police warrant cards by country
The card a plain-clothes officer or a federal agent shows at the door: his name, rank and service.
Bearer prints it for 2 offices: United Kingdom, United States. Each is read off a document of the time or reconstructed on the country's law, and says which.
Bearer makes an investigator's papers for Call of Cthulhu and any 1920s or 1930s tabletop campaign: the passport a consul would have filled in, with the visas and frontier stamps a campaign leaves in it, and the permits, certificates and tickets of the period, to print or to share.
