I tried looking through his old twit-pics, but I think it's been too long and the old ones aren't there anymore.
Anyway, any help would be appreciated - I know that things uploaded to the internet never really disappear, so it's just a matter of me tracking it down....
ETA: FOUND! Thanks zestyzorra !!
(It looks like Guy Bee is going to be at VanCon, and I thought it might be cool to get him to sign one of his teaser pictures...and I remember really liking that one.)
