Naked tax protest in front of German Chancellor's office
The messages on the big poster are "Reveal balance sheets" and "Unitary tax now" and "FKK for corporations"(in German, "FKK" refers to "Freikörperkultur," - a reference to naturists, or people who like to be naked. They want corporations to reveal themselves too.)
