Sao Paulo photographer Klaus Jürgen E.K. Mahrenholz visited Marilia circa 1955 and took a lot of shots of the young city. Now, Klaus has got a page on Facebook where he posts most of his stuff. Unfortunately, most of his material has deteriorated but some of them photos are still fairly good.
São Bento's snapshot has deteriorated badly, but one can still see how it looked like in 1955.
Rua 9 de Julho looking up to Avenida; Avenida looking East are pretty bad.
