I watched a couple of instagram live things he did and it looked like he had some print-making setup and what looked like some piles of books he was making. He even mentioned a book once or twice iirc. My guess at the time was that it was going to be a collection of those drawings, but that was well over a year ago and I haven’t heard anything more about it. There are probably some people here who keep in touch with him that know more. I’m a fan, but I guess not enough to reach out about it. I would probably buy a book of those wacky drawings he does. Kind of reminds me of some of Mark Mothersbaugh’s art.
