The 2018 Andy Tiernan Classics calendar showcases great 2-stroke motorcycles from England. With lead pencil and watercolor artwork by Mike Harbar, featured bikes include the 1924 Dunelt Model C, the 1929 Scott Squirrel, the 1940 S.O.S. Magnetic and more. Important dates in the U.K. classic bike scene are noted, and all proceeds from the calendar sales go to the East Anglian Air Ambulance, a non-profit ambulance service that has saved the lives of many motorcyclists. $13.20 (at press time).
