briefly played in narrow red stripes for the 1890–91 season, before returning to all-white the following year. The stripes returned in the 1892–93 season, with black shorts replacing the blue in 1904. The shirts remained largely unchanged until collars were first removed in 1955, replaced by V-necks until the 1966–67 season (when white socks were also used), and from here on the neck style varied. The traditional red and white stripes remained until the 1974–75 season, when elements of black were added, until the 1979–81 and 82 season kit. This was white with a red breast, and with thin stripes down either side, and was created to accommodate the logo of the club's principal sponsor, Cantor's, a local furniture shop. This was to be replaced by a striped kit, with the sponsor Bentley's (1981–82) and Renault (1982–83) written vertically down a white stripe over the left-hand side. Their kits continued to feature striped shirts, albeit with various aids to accommodate their sponsors, including a yellow square for Laver from 1988–92 (the 1990–92 shirt also featured narrow black stripes through each white stripe) and a black hoop, also for Laver in the 1994–95 season. Then came the diamond kit, which was so badly received that the club reverted to stripes the following season. Since then, red and white stripes and black socks with varying trim have been the order of the day, with black shorts for all but the 2002–05 seasons, when white and then red were tried. The club also every few seasons opt to put thin black stripes between the red and white stripes. Sheffield United's home colours were the inspiration for the kit of Irish club, Derry City. In 1934, Derry City adopted the stripes, while Billy Gillespie was manager of the club, in recognition of Gillespie's achievements at Sheffield United. The first time a crest appeared on the shirt was in the 1891–92 season, when a red crest appeared on the white shirt, but this disappeared the following season. United used the city of Sheffield's coat of arms from 1965–77, when a new crest was used, introduced by former manager Jimmy Sirrel, but designed apparently over 20 years previously by former player Jimmy Hagan. This consisted of two white crossed swords, or blades, the club's nickname, with a Yorkshire Rose above, on a black background. This is surrounded by a red ring with "Sheffield United F.C." written
