Redwall Collector Cards were first released in 1998 as a promotional Redwall item. They are unavailable for sale in any store, and were commonly handed out at bookstores when a customer purchased a Redwall novel. Collector cards are also currently given out to members of the Redwall Readers Club. The cards themselves are 2.5 inches wide by 3.5 inches high. There are two different series, British and American. A pack of the first 19 Redwall Collector Cards comes packaged with the Twentieth Anniversary of Redwall Gift Set.
