On Saturday 3 December from 1pm to 3, PJ Holden will be signing comics in the Forgotten Pelmet on Ann Street. That should include the first issue of Strip Magazine, in which he draws Black Ops Extreme. I'm sure you could also persuade him to sign recent issues of the Judge Dredd Megazine, for which he drew Numbercruncher, the miniseries Robocop/Terminator: Kill Human, and older stuff like Battlefields and Fearless.
Also, pub meet on Thursday! If you're in the vicinity of Belfast and make comics or are interested in making comics, we'll be at the Cloth Ear on Waring Street from 9pm. Here's the Facebook event page.
