Moebius is one of my all-time favourite artists. Escher rocked my world with his tessellating drawings when I was a kid - haven’t thought about him much as an adult, other than to admire his technical skill. Giger’s a little grotesque for me, but I once bought a set of postcards of his work so I could use them to write to a friend who was living with his ultra-devout aunt at the time.
