This is a pair of professional training stamps, first series, used by Empresa Brasileira de Correios e Telégrafos (ECT) (Brazilian Post and Telegraph Corporation). These were used for postal staff training. These are quite scarce, and seldom seen unused.

Mint, no gum (as issued), the stamps you see here are the ones you will receive. Due to the cost of this item, shipping will be by Canada Post Registered Mail.
