I just had to edit this topic and move this stamp here. From the looks and theme, I was sure it was one of the regional premium, 25 coins stamps - but the Slowly API shows it as a FREE issue. This stamp is likely to debut in Brazil, which has their Dia do Indio (Indigenous People's Day) on April 19. We should also see it later in North America, USA and Canada have Fall dates for this commemoration. ** We will be adding stamp event descriptions here later... **
