Brazil: Priority

Priority labels from Brazil. These are all black. I got them in 2020. They are from a sheet.

I'm unsure of the year they were published. The person that was kind enough to send them my way got 3 different kind from the post office. These, some blue ones I have already (and have posted) and some other blue ones that look to be from a roll, which I will post.

Year: ?, Self-adhesive.
