Imperial-Kino

This postcard is a photo that could be sent as a postcard. But unfortunately it wasn't send as a postcard. The backside is empty and you can read nothing about this cinema on the photo-postcard.
It is a riddle - and I love riddles and that is why I bought this card.

You can read at the card the name of the cinema: Imperial-Kino and the advertising for the movie Im goldenen Käfig (In the gilded cage). This movie - so I knew from Murnau Stiftung - was realesed in Germany on 5 October 1912, directed by Curt A. Stark, produced by Messters Projektions GmbH.
There is written on a poster inside: "Heute Preiserhöhung. (Today price rice.) II. Platz 25 ₰, I. Platz 35  ₰".  ₰ is a sign for Pfennig, a former German coin. 
So I know the cinema was situated in Germany and has opened about 1912.

Let's look for more information to Kinowiki (unfortunately, no longer reachable - very sad, irreplaceable)
Cinemas called Imperial worked about 1912 and later in these German cities:
- Dresden, Moritzstrasse 3, opened in 1908 as Imperial-Kino
- Löbau, Innere Zittauer Strasse, opened in 1910 as Imperial-Theater
- Munich, Schützenstrasse 1 a, opened in 1907 as Imperial-Theater
- Riesa, Poppitzer Strasse 2, opened in 1909 as Imperial-Tonbild-Theater
- Wiesbaden, Rheinstrasse 41, mentioned between 1907 and 1917 as Imperial-Biograph-Theater
- Freital, Lange Strasse 1, opened in 1911 as Imperial-Theater 
- Radebeul, Harmoniestrasse 14, opened in 1910 as Imperial-Welt-Kino
- Roßbach - today Hranice u Aše in Czechia, Hauptstraße 463, opened in 1910
as Imperial-Kino.

The only cinemas called Imperial-Kino were in Dresden and Roßbach. But Roßbach was a Bohemian town, has belonged to the Austrian Emprire until 1918. There they had no Pfennig as coins, but Heller. So the cinema at the postcard is the Imperial-Kino in Dresden.

The next question is: Who are the men in front of the cinema?
