Rio Marauia, Indio do povo Uaika da tribo Mokarinxinobeteri (Brazil)

In 1969, someone placed three large and different stamps on the back of this card. There’s no message or address, but there is one red postmark (from a postage meter) and one additional commemorative chop. Around the edges, there are also three small inked notations with numbers. Exceptionally, and all things considered, we assign Grade: 2
