I managed to snag one of these in excellent condition yesterday, but it is in the black/silver/tan colourway.
The border is black, the background is silver, then then "E" is coloured in white, and the "N" and "Z" are coloured in light tan. After I'd paid for it, I found myself hoping that its not a fake.
I had never heard of this colour combination.
I'm told that this is one of the harder ones to get (although not as rare as the black and white) and that is was a Yellow Label, which apparently means that it was one of the earlier releases.
It was also confirmed for me yesterday that black and white is extremely difficult to come by. The guy where I bought my copy said he has only had about 2 B&W through his shop in the 10 years that he's been there.
I've always wanted to collect these different colours but would only do it if I could get covers in really, really good condition.
Can't wait for this auction...
A black and white that's rare anyway would be even more unique with some sigs on it.
