When teaching went back to in-person instruction I would don this darth vader set-up. I would strip down upon arriving home and burn my clothes. No, actually my wife just made me shower before touching her or our daughter. This was during the time we would disinfect our mail.
So I started these drawings as transmission studies of the danger zones. I liked the image of the paper as barrier before the masks are placed. The super hero/villain configurations interested me.
