If you are looking for a calendar, and also want some art for your walls, consider my 2011 calendar.
It's a 12 month, January - December 2011 wall calendar. There are thirteen detail photos of art work I created in 2010 (twelve months plus the cover). It measures 13" x 10.4", and costs $30.00 plus shipping (and plus tax for Massachusetts residents). You can see pictures of each month and get more info here.
There's plenty of time to order one and have it arrive by Christmas, if it's a gift for someone. Or, if it's for yourself, and you don't need it until December 31st, there's even more than enough time. It'll take up to a week for it to arrive at your door, depending on where you live.
