I finally managed to track down a copy of the Skeletal Book (Swamp Version) last week. The envelope has some wear at the top, but the book/jacket are in perfect condition. The Hyperstoics and Sparrow books are great, but it’s nice to see Pus’s art in a little larger format. A few pieces in this one that I had never seen before, too.
I don’t know if I’m going to go completist crazy and try to find the Pusfan version; only time (and availability) will tell!
