My copy has the plate in the expected "golden" colour too. I'm looking at a fairly recent Egmont English-language version (2003 edition, second printing, bought last year): which edition do you have, Dark Gallon? As Maximus says, perhaps it is an error which has been corrected, or maybe just a flaw in your book?
Unfortunately these things do happen, and it is more likely to be a curiosity than a valuable collectors item as a result!
It's ironic that it is Black Island that it is in, because the first colour edition had many corrections made to the colouring when they came to do the facsimile, because over the years the printing plates had become worn with use, and they no longer registered properly. |
