Self-initiated project created by Petter Hanberger to have a tee as calendar (for the year 2009), so you can save some space on your wallet — instead of having that small calendar card.

A pen is also attached to mark the shirt. Although the picture only show that you can fill in one box for each day that the shirt is being used, I think you can use this calendar shirt as simple schedule-reminder or notes for the day. After a year, I believe this tee will be a piece of art — especially if you’re a very busy person.
