Stevie's artwork

[firefly15]

Couple questions for all you photo/image collectors:

Does anyone have a better version of this:


I've always loved this. Does anyone know the history of it? Specifically, how it wound up on the internet? Also, maybe this is a bit cynical, but do we know for sure Stevie painted/drew it? I mean, I know it has her signature at the bottom and the handwriting matches and everything but still, someone could probably fake that...
