The Great Blondie Comic Strip Crossover kicks up another notch today with a quick mention in B.C. and with many of the invited characters showing up in the Blondie strip. I think some of the guests aren't going to receive invitations in their strips until next week but, hey, these are the funnies. They're not supposed to be logical. I also don't understand how Garfield has suddenly learned how to talk. [NOTE: I'm going to try to link to all the strips involved in this event but some of them may be behind subscription walls or on sites that require registration.]
Yesterday, I posted this list of which strips are involved in the promotion and when. Apparently, the person who furnished it to me got it from the rec.arts.comic.strips newsgroup, mainly from a posting there by D.D. Degg. You should know that r.a.c.s. is a fine gathering place for fans of newspaper strips and a good place to visit if you have a question about that topic or if you just want to discuss them.
