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

Wordmark designed in collaboration by Facebook’s in-house design team and Eric Olson of Process Type Foundry. Details:

Eric Olson's Klavika was used in the original logo

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:

Several fonts capture the rhythmic tone of this lettering.
The closest might be Mister Sirloin

descender on _p_ replaced by descender from _q_

Lettering in the style of a simplified Tuscan.
Quadrille 2 could be modified to replicate the monogram.
For _L_ copy the top terminal, rotate 90 degrees right and use it to replace the teardrop.

Might be numbers resident in a machine for sequential numbering or physical numbers in a crash numbering machine.
Most people would not notice any differences from Prata, a free Google Web Font

With some distortion, esp. the top heavy _S_
Weatherly Systems did a version under the name Tolkein. Download is of doubtful legitimacy.

Knockout 68 Full Featherweight -- NOT THE FONT -- could be used "as is" for a fairly close substitute.

The _A_, _B_, _R_ and _O_ are geometric Art Deco.
The remaining letters look like Metro Two by W.A. Dwiggins

Still looking to see if this combination is a font.

Not a font. Note for example that, while the width of the vertical strokes in _L_, _U_ and _E_ are about the same, the ones in _B_ are noticeably wider.
Compare to Impact, with the width narrowed by 73.5% -- which makes the vertical stoke width the same as _E_ in YAMALUBE.



In the ballpark, but would need a fair amount of adjustment to match the YAMALUBE logo.

Other similar fonts, Helvetica Inserat & Compacta Bold.

Is this a photo of an actual leather-goods product?
Do you have any information on the source of the image?
The _c_ and the _s_ remind me of Rob Leuschke's FleurDeLeah -- NOT THE FONT used for _Success_ --

This is the famous font commissioned for The Times of London in 1932.
Available on the operating system for Microsoft computers.
Comment: very appropriate choice for artwork of a time piece

A lost Art Deco gem. Good find.
