So, I think I finally found the perfect 2010 wall calendar. It's from Linda & Harriett. The cost is only $30 (for a whole year!), for which you get 12 fully letterpressed months (each 9"X5.25") with gorgeous prints.
But the best part is that on the back of each month is a postcard image. So, once your are finished with a month, you can cut the bottom portion off and send it off, as a postcard, to a friend. How cool!
