This phrase from the comic’s lore has been spray painted around NYC and other cities. Many believe it’s a marketing campaign, not fan created graffiti. Does it even matter? If it was done by an agency or studio marketing department, does it cross the line? Does the fact that it’s a scrawled in spray paint instead of a neat stencil or wheat paste wild posting make a difference? All these tactics are illegal, so what justifies using them - effectiveness or aesthetics?
