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
