I am new to doing genealogy. So I apologize if I am asking what may be obvious to others. My grandfather had a nephew by the name of Erich Eichner who came to Rio de Janeiro >from Vienna Austria in the late 1920s or early 1930s. He started a bookstore around 1935 called Livraria Kosmos. My English and Portuguese attempts to contact this store (email and regular mail have gone unanswered). I believe he died in the 1970s and is buried in the Caju Cemetery. Is their a way to get a photo of the grave site or a copy of an obituary? Any help would be greatly appreciated.
