Charlton have used a number of crests and badges during their history, although the current design has not been changed since 1968. The first known badge, from the 1930s, consisted of the letters CAF in the shape of a club from a pack of cards. In the 1940s, Charlton used a design featuring a robin sitting in a football within a shield, sometimes with the letters CAFC in the four-quarters of the shield, which was worn for the 1946 FA Cup Final. In the late 1940s and early 1950s, the crest of the former metropolitan borough of Greenwich was used as a symbol for the club but this was not used on the team's shirts.
