You might also look at Herchey Serif. http://myfonts.us/td-vfkp8Q Note that it lacks a serif on the top rhs of _A_.

Derived from Clarendon, in the same way as fonts like Consort RR, Egizio Condensed, and Willow -- which are NOT A MATCH.

Much closer in style. Only offered as a distressed version.
No lower case.

This monoline script might be a custom production for the movie.
Emma Suárez has similarities to several fonts.

Wood-engraved illustration show the Remington New Model Army Revolver made c. 1863 - 1875.

which establishes an approximate date for the advert.
Bodoni Egyptian Pro ExtraBold could be used to approximate the bold font.
Further digging might turn up a closer substitute.

Not available for separate purchase.
Supplied with Microsoft products per the link.

Perhaps closer than either suggestion in terms of stroke thickness, letter width etc., a 50% blend of the two fonts:



Again, my opinion is that _la la land_ is custom lettering or a font made for the movie.

I suspect that _La La Land_ is custom.
Most distinctive letter is _a_ with it's angular diagonal.
You can get fairly close with Druk Condensed X Super, particularly if you clip the tail on _a_.

Thickening and minor changes to make it work on a store sign.
Available from various foundries.

SESSIONS
An American Typefounders 19th century font called Rodeo, and later sold under that name by Letraset as Rub Down Letters. Later names include Helvin, Red Dog Saloon, digitized by Font Mesa in 2002 -- link below, and 57 Rodeo, digitized by Baseline Fonts in 2002.

Clarendon is available in this weight from various foundries.
Linotype and URW call this one ExtraBold, Bitstream calls it Black

Emfatick NF is also based on Ed Benguiat's Caslon Black, but does not have the same _fi_ ligature.
It is an inexpensive substitute for your mystery font -- assuming it is a font and not a custom creation.
Photolettering seems to sell Benguiat Caslon Plain only by subscription.

The ball terminals on the ligature _fi_ and _c_ in Benguiat Caslon Plain are closer than Tiffany.
Set the word _fiction_ and the letterer automatically produces an _fi_ ligature.
But neither Benguiat Caslon Plain nor Tiffany are a perfect match to _fiction_.

In the predigital era this was sold as Cardinal by Letraset as rub down letters, without a copyright claim or credit.
Dan X. Solo knew it as Wedlock and sold it as a digitized font in the CD packaged with the Dover book on 24 Victorian Display Alphabets.
Aldus digitized Cardinal and this was ripped to make the font produced by Dieter Steffmann.
I don't know the name of the person who originally created the design.
Wish MF is an independent digitization by R.W. Mueller of Cardinal, or whatever else it might have been called in the predigital era.
So, several digital versions exist, and at this scale I can't say which one you used to write Tricheurs. Anyway, Wish MF would work fine.
