Because it was more obviously a period piece, and therefore a collector's item.
The publishers (not MT&LL-C, although they might have agreed) made the decision because they believed that any views or expressions in the book which might be deemed inappropriate in the Nineties, were clearly in an historic setting, and to be viewed in context.
It might be thought a little disappointing that the colour edition adheres so closely to the B&W version, because it could be thought that Hergé might have eliminated them when given the opportunity to re-do the book.
He could at any time have produced a totally up-dated version, using a less grotesque style for his black characters (a la how he drew them in Red Sea Sharks, although even there it can be seen as problematic), and giving them a strong rôle.
However, as he didn't, the book had gained the slightly mythic quality of any item which is suppressed. Putting out the B&W edition in English was a compromise position: allow the book out in English, but minimise the chance of offense with an introduction stating that the content could possibly be seen as un-P.C.
As it happens, the public seem to have accepted the situation, as no complaints were received. |
