the book I have then is most likely the 1989 Sundancer edition
Well, really the only way to tell is to open it up and look inside... ;-)
Perhaps confusingly, I've just had a look in mine, which is
definitely a 1989 Sundancer copy (that's when I bought it), and the ISBN given in the publication information is 0 9512799 1 2 (make of this as you will - I didn't write the book's page on this site, so I don't know when or where the ISBN information given there came from, I'm afraid).
What does your book have to say on the subject?
As to the appearance, well, the images in the book guide show the English-language covers we have had, which reflect various early editions in French. If by "match" you mean have a uniform spine colour and cover design on your book-shelf, then I'm afraid you will be disappointed, as that never happened for the black-and-white books, even in French.
The only one really "missing" would be a white-covered "facsimile" of the first cover for
Tintin in America which had a different picture by Hergé, which has gone on to prominence because it set a world record for the price of a piece of comic book art when the gouache painting used on the cover sold at auction; other than that, what we have matches the non-uniformity of the books when they appeared.
They settled down into the yellowy-brown cover with red-cloth spine for the last few black-and-white books, which is what has come out in French, but we've not had them all, as yet, in English.
