This is a complete vintage set of four promotional drinking glasses released by Burger King in 1985 to commemorate the 'Mark Twain Festival Summer'. The set comes housed in its original cardboard carrying case, which features the classic Burger King logo and festival branding. Each glass is decorated with colorful, detailed illustrations depicting scenes and characters associated with Mark Twain, including a portrait of Twain himself, Huck Finn, Becky Thatcher, and a scenic cabin/riverboat illustration. The glasses are made of clear glass with vibrant green, blue, brown, and white screen-printed graphics. The original cardboard carrier shows some light age-related wear and discoloration typical of its age, but remains structurally sound and holds the glasses securely. This is a fantastic nostalgic collectible for fans of vintage fast-food memorabilia, advertising history, or Mark Twain literature.
