Cobb question - Sort of
 

I've heard of Ty Cobbs thing for using green ink, and an item in another collection of mine got me wondering.

The addressee is Governor Howell Cobbs wife, and the period is while he was governor. (And they're not related to Ty) What got me thinking is the green cancel, which is pretty rare.

Is there something about Georgia and green?

And does anyone know about why Ty Cobb used green ink so often?
