sentences:  Although the club did not traditionally sport a crest on the club jersey as the concept had not yet become popularised (probably due to the complications and vast time-consumption involved in mass-producing intricate designs before greater technological advancement occurred), throughout the years playing in the Irish League - and for most of the first season in the League of Ireland - Derry City used the coat of arms of the city, rather than having an exclusive crest of their own.This crest often appeared on club memorabilia such as scarves, hats and badges.The symbols on Derry's arms were, and still are, a skeleton, a three-towered castle, a red St. George's cross and sword.
