It may be half of a double-sided hangtag. These sometimes came unglued. Someone may have "repurposed" both halves to create two separate hang tags. I would just gently hand wash it, dry it flat, and then condition it.PERFECT. I was digging for this. Thank you so much. ETA this particular Station has a hangtag that is very thin and not dyed on one side. I'm curious if that is what pre-1994 hangtags could be like or if it is a fake but regardless, should I dunk that as well or would it ruin it being so thin and only half-dyed?
ETA: or you might not even need to wash it if it looks OK. Just condition the stamped side.
