This was the uncopyrighted shirt crest of Arsenal Football Club created created in 1935 and re-used for the 1952 FA Cup final. 
In accordance with section 12 of the UK Copyright, Designs and Patents Act 1988, and because the author of the original work is unknown, copyright expires seventy years after the work is first made available to the public.

Since the club has admitted the crest is ineligible for copyright, it has been given the {{Insignia}} image tag.
