The origin of the term is unclear but may derive from the two clubs' initial match in which the commentators referred to the teams as "like two old, firm friends",[8] or alternatively may stem from a satirical cartoon published in a magazine prior to the 1904 Scottish Cup Final between the sides, depicting an elderly man with a sandwich board reading "Patronise The Old Firm: Rangers, Celtic Ltd", highlighting the mutual commercial benefits of their meetings.[9][10] The name may also be a reference to these two teams being among the original eleven members of the Scottish Football League formed in 1890.[11]
