Psych! I know you were totally fooled, but these are photographs of Stasi officers participating in a course called "art of disguising." In fact — I know this will come as a shock — the first two photographs are of the same guy. Don't act too surprised!
The photos, discovered by Berlin-based artist Simon Menner in the Stasi archives, are from an internal course called "art of disguising" (and what an art it is!); Menner has an exhibition in Berlin at the Morgen Contemporary called "Pictures from the Secret Stasi Archives," featuring these photos and others. (Also included: "snapshots of private homes taken by Stasi agents before they conducted secret searches," used to restore an apartment to its pre-search condition.)
