Assembling flat-pack furniture with a hex key. Sun variant: disc ringed by hexagonal bolt heads. The real Euoplocephalus (say it YOO-oh-ploh-SEF-ah-lus) lived in the Late Cretaceous — armored everywhere, including bony eyelids. Drawn in the Kaiju Sunrise style: dense ink, hot vermillion and pink, halftone skies and woodblock waves, like a 1970s Japanese monster poster shrunk to vinyl. Matte vinyl with a protective laminate — it survives water bottles, dishwashers and about three years of direct sun.
