The clip is of Avenida Central, now the pedestrian boulevard, in 1958. Interesting note of the Imperial beer crate used by the traffic official and the Sears building; the shot of the Cine Rex, now a McDonalds, diagonal to the Parque Central.
The march through the streets is of Rafael Angel Calderón Guardia and his Republicano Nacional party.
