Brazil Retro Replicas football shirt 1984

1984 Brazil retro replicas football shirt. I don’t know much at all about this shirt – I’ve never seen one like it before. The badge design and the collar would date it at around the mid-80s, but I’ve never seen one with the broad stripes at the shoulders and the pin stripes round the rest of the shirt. I think this actually dates from the mid-80s (if so it’s in great condition for it’s age), but I also think it’s probably a “fan shirt rather that a replica of one actually worn by the team.

It's an acrylic shirt made by a company called Tapajos.

Any further information would be appreciated.
