My fellow 2000AD Forum members do a fine Advent Calender each year. Chocolate free and full of 2000AD goodness. At least one treat per day (sometimes more).
The readers of 2000AD include some very talented folk and it is well worth a look.
Here’s a link to it – 2000AD Forum Advent Calendar.
And to tempt you here is the offering from Michael Carroll. Michael is not just a Forum member, he writes Judge Dredd on a regular basis for 2000AD.
