This is a clipping from a 1949 British magazine, photo taken probably in November, 1948.
And a photo used on the cover of a Chicago Tribune supplement, dated November 28, 1948, from the same photo shoot as the one above with a significant color shift. Guessing the true color is somewhere in between. Dig the clouds used as a backdrop in the photos.
And, lastly, a third photo from the shoot. Not in color (well, except for the blue tint), but too nice a photo not to include it.
