Cool to look at these all again. I like number 47 a lot. That being said I think the art on the WITK is awesome a really beautiful in person. I really like # 42 as well. I wouldnt pick it as a winner for this competition but I like the understated design.
If I were going crazy, I think #33 works the best when translated to both the frame and box. Has the artist's flare, while still being Oakley and not a vanity piece. However the #48 halftone pattern one would be very cool if it was a standard release and they threw a non-premium price tag on it or something.
I would probably seriously enjoy at least a half dozen of these. Quite a few are just out there ... cool, but out there. I like 37, because who doesn't want more woodgrain. And 40 is cool, even if it is reminiscent of the London Police pair.
