California artist Clinton Fein is used to getting flak for his blatantly political and often shocking artworks. But this past week, Fein found himself on the receiving end of a protest from an unlikely source: the printer he had hired to produce his giant prints. The online printing company Zazzle rejected two of the pieces Fein submitted, claiming that their ultra-provocative content violated their standards. Fein is accusing the company of censorship; Zazzle says it’s a perfectly understandable business decision.
