Awesome...that's my kind of find (or wish it was).
Yesterday I had a small thriftening (I needed one)
Hermes, Recent Stefano Ricci x2,Older Ricci, Giani Versace (@SpooPoker could this be pre-death?), Brioni (found a small snag on this one),
Polox Corn Khaki Cotton Suit and EZ sort of bomber
Flannel Isaia Suit (needs some dry cleaning on the pants)
Without seeing the actual artwork *ahem* the letters and additional punctuation makes me suspect this is maybe Inuit or some other northwestern indigenous name.
