I wasn’t familiar, but I am a fan now that I’ve seen some of it, definitely going to be inspired by lots, really excited to dive in more, thank you for this!
I have a whole collection of vintage SF paperbacks that feature his cover art. It’s a very niche fandom of people (probably dudes) who grew up reading these books in the 60s and 70s.
I don’t mean to say that women didn’t read them, but other than my wife, whom I introduced to Powers, I’ve mostly only met guys my age into the book collecting.
