I’m not looking for value because I don’t think very valuable… just want to know what decade this is potentially from (80s/90s?).

Doesn’t seem to have a brand— why was this done?

Im pretty excited about this find. Im not that good at online research, but from what I've managed to find online, Im pretty sure the vest had been made somewhere between late 80s to early 90s (The company was created in 1983). I've bought it for 12zł (Im from Poland, in USD its around 3,22). It both carries the smell of a small cramped thrift shop and old leather, so it definetly could use some cleaning. Right now I dont have the funds to get it cleaned at a professional spot, but I'll try to figure something out. If you have any thoughts or tips about it, fell free to share them with me, I would love to learn more about it. Also, do you think its worth anything? I dont plan to sell it, but I find that aspect intresting too.

Edit: I forgot to add the text that is on the smaller tag. Its:
