A series of these purple masked crusaders have been showing up in clusters on the streets of Los Angeles recently. Titled cryptically with a HELP, this has the looks of the start of a street campaign. We have no details for you yet, but what we do have are several of these signed posters to giveaway to some of our readers. Just leave a comment as to which artist you think is behind these works and the first ones to get the answer correctly will have these mailed out to you next month.
