I have seen 6 different promo/business cards which UK dealer Telly Mania produced related to the 1960s Prisoner TV show.

Map of the village. Advertises his Etsy store

Mostly the same front as the one above. Back advertises PortmeiriCon in Wales, 2025

A bunch of people walking around. Back advertises the 2024 show at the above location

People in robes. Back advertises the 2025 show

Two promos which have the same fronts as the 2025 show cards, but the backs advertise the 2026 show instead
