1955 Bowman question

Spahnfan

In the scan below on the left border I see a difference in the separation color of this card and the card to the left that would have been on the sheet to be cut. One one card the separation line is black and on the other card the color is light brown. Any significance to this other than on different print runs they had different colors to separate the cards. The light brown I see fairly often, and the black not often at all.

I do not think there is any significance to the difference -- but you are correct, the light brown is seen about 95% of the time.
