San Telmo, Buenos Aires.
As a tradition, when I am in BA (with my parents) I usually visit the Feria de San Telmo which runs every sunday from 10am to 4pm at Plaza Dorrego.
This time I stopped at this stand that took me to my childhood where this kind of phone existed in my house.
This is an antique fair with more than 250 stands. It was created in 1970 by architect José María Peña and it is visited by 10,000 people every sunday.
