T206 Neal Ball with odd Blue/Green outline
 

I picked up this ball that a seller had listed as altered. He only
provided a small scan but to me it didn't look like someone drew the
outline on the card and it was cheap enough so I purchased it.

I'm trying to figure out what would have caused the outline. I
don't think it's a normal shift or blue would show in the white border on one
side and you would see a difference in color on the edge of the
image on the other side. It's also shifted in two directions side to side

I would appreciate any opinions on what might cause this
type of outline.

honestly, it looks like someone sketched over it with a pen out of boredom.

And that someone has a blue fingernail fetish.;)

Looks like someone put a piece of carbon paper over it and traced on it.

My first thought was Crayola.

Gotta say that's exactly what is going on here.

Not disputing that possibility or fact. Kinda a cool but QC back then wasn't very good, I don't think. Or if it was a fair amount of scrap type cards made it out the front, back and side doors. :)
