Built during the 1930s, when Argentina's economy was the tenth strongest in the world, the Kavanagh Building was one of the world's first reinforced concrete skyscrapers and for many years remained the tallest building in South America. Commissioned by Corina Kavanagh and designed by architect Sanchez Lago y De la Torre, the 31-story modernist structure juxtaposes five volumes in a triangular, stair-like configuration that served for many years as a representative symbol of modern Buenos Aires.

The ballpoint pen invented by Ladislao Jose Biro was originally patented in Hungary in 1938. The principle of the ballpoint pen was originally patented by John Loud in 1888 for a product to mark leather and in 1916 by Van Vechten Riesberg, but neither of these products were exploited commercially.
As a journalist, Biro was inspired by the concept of quick-drying ink in a print shop.
