Looks pretty good, but the two holes (large one on top small one on bottom) obviously lower the value for some collectors; mostly (for me) due to the yellowing at those two spots.
The uneven yellowing of the box will definately look worse the longer it is allowed to yellow unevenly.
I think the best remedy for that one is to be stored in a
SW Vault away from damaging light sources.
If I wanted one, I would pony up $275 (plus SH) for that
OCE 6th Print OD&D White Box Set in Shrink Wrap.
The Minty (no
SW)
OCE I have now is good enough for me though.
Good luck...
