Columbia 2 Eye Question

After removing "Another Side of Bob Dylan" from the platter this morning, I noticed something odd.

The "360 Sound Stereo" printing across the bottom is black on this record. I purchased this on release in August of 1964.

Now, I have literally hundreds of original 2 Eyes from the 60's including Dylan, Simon and Garfunkel, Super Session, Electric Flag, yadda yadda yadda and this is the first label I've seen with black printing. For those of you old enough, you know that almost all have white printing.

So, I started looking at all of my original 2 Eyes and can't find another with black printing.

Anybody know the significance if any?

I also have a Dylan album in a mono cover with a mono label that is clearly stereo but that's for another day.

Thanks in advance.
