DCA-201 (for Disney California Adventure and 2001, the year it was opened) pin, one in the series of 24 Cars Land mystery pin. A Walt Disney Imagineering (WDI) exclusive sold at the 2011 D23 Expo at Anaheim, California. Measures 1.5"x.75". Released August 19, 2011; a Limited Edition of 200. Mint condition, opened only to determine which pin it was. I always combine multiple items in one package and refund the excess postage paid.
