C&V Cycle Calendars
 

I just picked up two 2011 calendars featuring classic and vintage bicycling posters from Amazon. Actually from a reseller on Amazon. Just do a search on Amazon for Bicycle Calendar. Watch the prices and shipping charges as some vendors are more expensive than others.

It's not a current one, but my boss gave me a Portraits of the Tour De France 1999 calendar. It sits at my desk and I occasionally pull it out just to stare at pictures. It's an awesome calendar.
