Well, in my case, it's a little unnerving, because it really is about me. The woman on the billboard is my mother, reworked a bit. I think she was 17 when she posed for that label. It wouldn't be the first time I've had an experience like this (Mother in a 1940's nurse's uniform with glowing green eyes was weirder). It's what I get for having had a mom who was one of the top models on the west coast. But it's both fun and unsettling to nod hello to my mother on the way to work, every day.
(She said she had the same sort of experience once, finding herself fifteen feet tall as a sculpture of Demeter holding a basket of fruit...)
