I came across an amazing Batman Advent Calendar available on Etsy. It features twenty-four amazing colored disks, each adorned with the likeness of one of the classic characters. The board itself features a skyline of Gotham, complete with the Bat-signal.
Even if you’ve started Advent for this year, you can still use this calendar as a great Christmas present for your favorite geek or geekling. I know it’s made my list. The seller, CultureCal even has a Zelda calendar!
