Official art of Mumbo’s chair?

I’m putting the finishing touches on my Lego version of Mumbo, and would like to look at all official and/or licensed depictions of his chair.

As far as I know, Mumbo’s chair has never been seen in any promotional render. I’m aware of only the following portrayals:

• The First 4 Figures sculpture
• The German language comic
• And of course, the in-game model itself

The giant Mumbo statue from E3 is also seated on some sort of chair, but it bears (ha) little resemblance to the one in the game.

Did I miss anything? If so, please send it my way.
