To me, what's interesting about this clip is that it shows just how far and wide Brooks' films were distributed. [I also found clippings and advertisements for a few of her American silent films, as well as the German made Diary of a Lost Girl.] Also, I don't think I had ever seen the image on the left, of Brooks leading a German Shepard. It is, in all likelihood, a rare German publicity photo.
Pandora's Box debuted in Latvia in March, 1929 at the Splendid Palace theater in Riga. It debuted as Die Büchse der Pandora (from Wedekind's Lulu), as can be seen in this newspaper listing of movies playing in town.
[ 01/09/13 Addendum: I have been told that Die Gottin der Sunde may translate as The Goddess of Sin, which makes sense.]
