I don’t remember where I’ve got the lady from, that’s on this school bag. But it has to be from one of those comics, that were around, back in the 80s.
I later wrote over her, in a moment of anger.
The surface has been primed with ordinary spray paint (aerosol paint), before it was painted with Uni Posca markers. This way, you get a much better surface to paint, and you prevent the colors from sinking into the substrate and it also serves as a unique background with a good contrast to the “piece” itself.
