The Washington Post's Book World lists a signing by New York Post cartoonist Sean Delonas and his son Ryan. They've coauthored a children's book, Scuttle's Big Wish. The signing is at Aladdin's Lamp Children's Bookstore, 2499 N. Harrison St, Arlington at 11 am. For some reason they're asking for an RSVP (I've not been to the store - perhaps it's small) - 703-241-8281. I'm not familiar with Delonas' work, but I think I'll try to attend this.
