I was thinking other pic perhaps Jabos, but was hoping for a late Vitro instead; but on this one? I have to grudgingly admit I really really like it. It doesn't seem in sync with the others I have for some reason. More understated elegance than the "siss, bang, boom" stuff (like the ones before this but not as much).
I wouldn't have guessed it by the colors, but I see the clumpy green aventurine and combine that with the single fold construction and it has to be Jabo.
