sertanejo. Rustic, back-country, rude.

A discovery that for me would become Art Déco Sertanejo occurred in June, 1972, as I was walking the streets of Caruaru , Pernambuco.
"Buttoned" houses, "Striped" houses, houses "wearing ties"...
what style was this? Back in Rio de Janeiro , none of my architect friends could give me an answer.
The Northeast and the style remained on my wish list.
In 1979, in Campina Grande , Paraíba, I found similar houses again, as well as signs, furniture and objects.
I started to research, photograph, and compare the things I saw in the city with other examples of Art Deco in the world.
But no one in the city had any registry, names, data or dates.
