Hot Shot News (official Japanese site) has two new reports up. Haven't fully translated them, but here is the general gist.
First, an exhibit of Monkey Punch's artwork will be shown at the Saitama Municipal Cartoon Museum. It will open November 25 at 16:30.
Saving the best for last, a new OVA "production commemoration talk event" will premier at the Akiba 3D Theater in the Tokyo Anime Center. If you are in the area (lucky bugger!), the curtain will open on October 21 at 13:30. Looks like the production staff will be on hand to talk about production of a new Lupin OVA. Can't make out right now who will be there, but I will be keeping an eye out for more details.
