“Brothel badges” were pornographic (by Victorian standards, anyway) badges that parodied the “pilgrim badges” sold at shrines to religious pilgrims in earlier times. Historic Games sells replicas of the badges for $6/each, noting that historians differ on whether they were naughty Mardi Gras souvenirs or brothel tokens. Of this badge, “Lady,” the site notes that it’s a “lady… off on pilgrimage, carrying a pilgrim’s staff with a phallus-shaped head, and carrying a rosary. Similar badges were popular in the Low Countries from the 13th through the 16th centuries.”
(Thanks, Chateau Bizarre!)
Update: A reader sez, “These are suspiciously similar to the badges made by a friend of mine at Fettered Cock.”
Update 2: Charles from Historic Games confirms that they’re the same thing — Fettered Cock is his supplier.
