Vintage 1989 100 Year Cadbury Chocolate Covered Biscuits Commemorative Tin

Only the tin, no cookies / biscuits inside. The tin is decorated with images of a variety of advertising ephemera / motifs from throughout the 100 years of Cadbury's operation. The tin is from the late 80s, specifically 1989. Some discoloration on the top from a piece of tape I peeled off. See pictures.
