Just another day in the Anonymous mines

Guy Fawkes mask factory, photographer unknown (please comment if you can identify her or him).

Update: A hint from the comments led me to the source of the photo: an article from Extra Online by
Fabrício Provenzano. The photo is by Gabriel de Paiva — click through to the article to see the uncropped, full-size version.

(Thanks, Fipi Lele!)
