A couple of years ago, I decided to make a point of choosing a different theme for my wall calendar each year.
For 2006, I selected an antique maps calendar published by Barnes and Noble, New York. For 2007, I selected an Australian outback calendar published by David Messent Photography. Just this week, I have selected a 2008 wall calendar. It is a camouflaged animal theme published by Workman Publishing, New York.
Here is a photograph showing all three calendars.
