 At the home match against Sunderland that year, the turnstiles were double-checked prior to kick off and were found to have been tampered with, ensuring that Everton had been defrauded of approximately 15% of the gate money actually taken.Following the implication and arrest of 15 employees (including turnstile operators, equipment mechanics and groundsmen), Everton introduced meticulously detailed gate books as well as new turnstile equipment.The collection includes two of these gate books, detailing receipts for each individual turnstile for every match played at Goodison Park from 1907 to 1911 and 1916 to 1921.
