* This picture has been sent to me by Eduardo Restuccia from Montevideo, taken with a similar camera on the same spot but 40 years later!
Looking south at Monumento del Entrevero (that is the fountain/monument). Entrevero means mix up or something similar, because of all horses and riders in those positions.
This is Fabini square (sometimes wrongly named Del Entrevero square - even in google maps).
