Movember is a celebration of Mustaches and men are encouraged to grow their mustaches (or just not shave them) during November. I had to look up the origins of this kitschy holiday and it seems that it was started by the Australian blokes in 1999 to raise awareness about men's health issues such as prostate cancer and depression. I know that Americans celebrate it because American men love any chance they can get to grow facial hair and live out their Paul Bunyan dreams.

I've created a design called Mister which will be featured in my etsy shop (here) for the month of November.
