Unknown Teak Hi-Fi/Credenza  

I just realized the green Global International Bonn sticker is on the inside of the cabinet, on the back panel. That doesn't make sense for a shipping label. I have no idea what sense it makes at all.

Client request, possibly. Some can be quite particular, though I agree the location seems unusual.
I spent a few years working for an international fine art transit company and I'm pretty sure it's a shipper's inventory tag. Customs agents tend to really like numbers that match documents.
