If this comic looks familiar--more familiar than the "Barbara marks" comics usually do, that is--it's because it's a callback to the very first comic in the series, which was published on Saturday, December 2nd, 2006.  I may or may not get one more marking comic in before the comic ends, but in case I don't, I want things to come full circle.  I've also returned to the original colours (I altered them a bit in later comics because the original colours didn't contrast enough).  Comparing the two comics will give you an interesting look at how my portrayal of Barbara has changed over the course of the last seven years.
