It's a rumour/legend popping-up every now and then about Abby Winters posing herself. Most of the time it was Susie allegedly being Abby Winters.
As far as I know Abby Winters did never pose, nor have I ever seen a picture of her.
Some people even doubt that Abby Winters is real.
The 'big man' behind Abby Winters sites like AbbyWinters, ISM and GOW is a guy called Garion Hall
