San Telmo ("Saint Pedro González Telmo") is the oldest barrio (neighborhood) of Buenos Aires, Argentina. It is a well-preserved area of the Argentine metropolis and is characterized by its colonial buildings. Cafes, tango parlors and antique shops line the cobblestone streets, which are often filled with artists and dancers. A street named the "Illuminated Block" is where many of these important historical buildings can be found.

San Telmo's attractions include old churches (e.g. San Pedro Telmo), museums, antique stores and a semi-permanent antique fair (Feria de Antigüedades) in the main public square, Plaza Dorrego. Tango-related activities for both locals and tourists are in the area.

At one of the “puestos” I spotted an old box camera. I haggled with the man and bought it for about ten Dollars. What was surprising about this German-made camera which used 120 format film (taking pictures that are 6x9 cms) was that there was roll of film in it. I was curious and promptly forgot about it.

A week ago while suffering the doldrums of extended rainy and grey days I wondered about the film.

I carefully wound the film back. When I took it out it was Kodak Verichrome which I know to have been a b+w film introduced around 1912.

 Of the camera I looked it up and found this:
