I came across Montserrat a few months ago while researching fonts for a new project.
Montserrat is an old neighbourhood in Buenos Aires where I spend a few years of my life while finishing secondary school.
Julieta Ulanovsky has this to say
The old posters and signs in the traditional neighborhood of Buenos Aires called Montserrat inspired me to design a typeface that rescues the beauty of urban typography from the first half of the twentieth century.
Milonga is a newish font (I think) from Pablo Impallari.
The font is inspired on the hand painted lettering and decorations that used to be very prominent in Buenos Aires called fileteado porteño and that sadly have been replaced recently for more modern and cosmopolitan signage.
You can see the influence in the termination and some of the ligatures. I really like this font for headings, branding and anything that needs to be highlighted.
Upper-case letters are particularly beautiful.
A very delicate script with hints of fileteado. La porteña
Also from sudtipos, Tanguera brings some of the style from older signs you can see in Avenida de Mayo y San Telmo.
