T206 printer's marks question
 

Are T206 printer's marks on the front of the card always black? If not, what other colors are known?

I would guess they are registration marks used to line up the colors, so any color in the card is possible. This mark is blue from Waddell Portrait.

Red

Here is yellow (top border)

I once owned a Proof that had 6 different colors iN each of the X ~ Y Axis's Cross~hairs... 10 years ago, He was the Only None Southern Leaguer Proof to exist... I do believe it's still true!

He's resided iN a Private Collection ever since I "Accidently" Sold'em :rolleyes:
