The purple circle background is going to need to be 4" The size of the the entire original scan is only 6 1/2" Not sure what the black blob is either but thought it was more hair. I have been trying to figure it out also for a while now. I played with Photoshop and tried to clean it up and came up with this. Didn't spend that much time on it but it is a start I guess. Anyone that is better at Photoshop go for it I have never taken that much time with it to get that good with it.
