the factories and foundries of the Black Country. Club historian Tony Matthews, however, suggests that it derives from the "bagmen", who carried the club's matchday takings in big leather bags from the turnstiles to the cash office on the halfway line. Other theories relate to the baggy shorts worn by various players during the club's early years. The official club mascots are named Baggie Bird and Albi; both are based on the throstle depicted on the club crest. Rivalries Historically, Albion's greatest rivals were Aston Villa from nearby Birmingham. The two clubs contested three FA Cup Finals between 1887 and 1895 (Villa winning two and Albion one). More recently, however, some Albion fans tend to see Wolverhampton Wanderers as their main rivals, particularly as between 1989 and 2002 Albion and Villa were never in the same division, but Albion were in the same division as Wolves for 11 out of 14 seasons. This had led to Aston Villa supporters now considering Birmingham City to be their fiercest rivals. A less-heated rivalry also exists with Birmingham City, with whom Albion contested the 1931 FA Cup final, as well as a semi-final in 1968. A number of hooligan firms associate themselves with Albion, including Section 5, Clubhouse and the Smethwick Mob.

The two sides have played each other 160 times, with their first major clash being an FA Cup tie in 1886. Both Albion and Wolves were founding members of the Football League in 1888, making the derby the joint oldest in English league football. The rivalry came to prominence when the two clubs contested the league title in 1953–54, and during the 1990s it intensified to new heights among supporters, with both clubs languishing in Division One for much of the decade and only local pride at stake. Moreover, in 2002 Albion came from being 11 points adrift to overhaul Wolves to gain promotion. The rivalry was further heightened after the sides met in the play-offs in 2007. A 2004 survey by Planetfootball.com confirmed that the majority of both
