A drawing of the Ducal Mansion appeared on millions of packets of rolling tobacco and cigarettes made by John Player & Sons, a Nottingham firm. Most packets had the phrases "Nottingham Castle" and "Trade Mark" bracketing the image of the non-fortress-like structure. This led the novelist Ian Fleming to refer to "that extraordinary trademark of a dolls house swimming in chocolate fudge with Nottingham Castle written underneath" in "Thunderball", in the knowledge that his British readers would be familiar with the image.
