I've not 'marked' it personally myself. If anything, in her time with me, she has become whiter as I rub the surface layers off (especially the neck). It's not just yellowing nitro; quite sure there's a significant contribution to the colour by the smokiness of Montreal clubs (they now have banned smoking in bars like just about everywhere else on the continent, but , they're French so they were the last to do so - at the time of acquisition, they still had not). Never seen a yellowing so dark (and we've seen quite a few of these white hobbits since I got mine).
