The sender made this card using old postcards she has received but has no where to store them. Clever!

This is a hand-tinted photograph entitled The Rebel  (1991) by Shelley Niro. Niro is an Indigenous filmmaker and visual artist from Canada. She was born in Niagara Falls, New York, in 1954, but grew up on the Six Nations of the Grand River Reserve near Brantford, Ontario. Niro grew up entertaining her siblings with songs, storytelling, and picture drawing. Her family would make appearances in her art.  Niro is a member of the Turtle Clan of the Kanienkehaka (Mohawk Nation) from Six Nations of the Grand River.  The model on The Rebel  was Niro's mother. The photo can be found in the Canadian Museum of Civilization in Gatineau, Québec. 

I think this is a tourist promotional card. On the back, there is information about the photo pre-printed in three difference languages - Portuguese, English, and Spanish.  The photo shows Liberty Square in Belo Horizonte. It reads A Cultural Heritage of Belo Horizonte, the charming Liberty Square gathers around it a diverse architectural landscape, including works by Oscar Niemeyer. A choice for leisure and culture, the square has been a part of the city's history since its foundation.
