Very interesting indeed. How many people have such secret treasures?
In a much less relevant scale, I have many photos taken by my father, from whom I inherited the passion for photography, showing many places in Rio, some of which have changed, some that no longer exist, even some historical things such as the construction of our first skyscraper. He also took some nice photos of other cities in a cruise along the coast of Brazil up to Manaus in the Amazon, that was in the early 40s. I want to have all this material preserved.
