See the cover for Tintin in America? It is not the cover I'm most familiar with, shown here:
I wonder what prompted the new cover? Instead of Tintin tied to a stake (which, by the way, is an inaccurate or misleading bit of info about Indians that was popularized by Westerns), we see Tintin riding a horse. Here's another version of the on-a-horse cover. It is the one offered at Amazon:
In doing an Internet search of covers for Tintin in America, I came across a couple of others. This one has a "II" after it, so maybe there's a Part 2 for this particular book in the series.
And this one, according to a fan, is the original cover. The original artwork for this cover was recently sold for $1.6 million dollars.
The Tintinologist site has a great deal of information about Tintin in America, including the changes publishers wanted made:
Finding a publisher for this book in the USA was impossible. Even in the mid-1940s, American publishers insisted that Hergé replaced the 'coloured' people featured in the comic with 'whites'. Then again, the USA was not the only country that gave Hergé a hard time publishing this comic. Most foreign publishers (i.e. non-Belgian or French) seemed to have problems with the almost apocalyptical scene in which the soldiers move out the Indians of the reserve, and the speed in which the new town is created.
I've got to do some research on Tintin in America...
