Clorindo Testa worked on the Bank of London and South America in Buenos Aires from 1959 to 1966. Seven years, and it remains one of his best-known projects in the city.
On the Divisare page where the originals turned up, Federico Cairoli is credited next to Testa. The photographs are by Cemal Emden. The old post's caption also gives 1970 in its title, but the project dates in the same caption are 1959–66, so those are used here.
