It's the outline of a woman lying on her side. I use it as a Rorschach-type test, though. I like asking people what they think it is. Most say waves, hills, or birds. I like all those answers, so I'm happy it looks like a lot of different things. It's a little over 2 years old. the outline is still perfect, but it needs a little touchup in the middle of the thickest part, where it's a little bit pale. It isn't exposed to a lot of sun, and I'm diligent about putting on sunscreen when it is. The one on my neck, on the other hand, gets slathered SPF 45 daily. I don't want that sucker to fade!
Oh, and I'm sure you can imagine how pleased (NOT) I was when the 24/24 milk campaign came out..... but it was MINE first!
