I realize that part of the 'New York' shows up in all of the T206 'St.L' variations, but not nearly as much as in the Coupon. It's as if they cleaned up the 'New York' plate all over again and didn't do as good of a job. The poor job makes sense, but using a different plate (other than the T206 'St.L' one) doesn't...to me, anyway.
The Polar Bear white ink theory is an interesting one. Maybe Steve can comment on that.
This stuff is what makes the T206 set interesting to me, even though it's like hanging out with the peasants to some vintage collectors
