Druk  Suggérée par donshottype 

Berton Hasebe, designer of Druck, produuced by Commercial Type, created some extremely narrow widths as part of his package of Business Week Druck, which is now used in _Bloomberg Businerss Week_.
The narrowest, BW Druk XXXX Condensed

is thicker and wider than the Berlinart poster.

I have not found a closer approximation of the letters of _YOU ARE_

However, this seems moot, because the letters of _YOU ARE_ show reverse contrast, i.e. the horizontal strokes are thicker than the vertical strokes.

IMHO it seems unlikely that there is a font that matches the letters of _YOU ARE_ without some compression.

To remove the reverse contrast effect from _YOU ARE_ we can try reducing the height of the letters by 50%, so they look like:

On second thought, a height reduction of 50% is too much, because it transforms _YOU ARE_ into thick and thin (stressed contrast) letters.

The most common design for a Sans Serif is the Grotesque proportions found in Druk, Knockout, etc.

Perhaps the best image to use in searching for a match is _YOU ARE_ with the height reduced to 75%, which has the usual Grotesque proportions



BW Druk XXXX Condensed is closer to this image, but is NOT THE FONT.

We should also consider the possibility that the letters of _YOU ARE_ were drawn by hand as an art illustration exercise
