They only fit three letters on the book in Barbie Keller's arms, and after putting the zoom at 500%, I could read the letters "B-R-L."

Which may be the abbreviation for "Braille," (the indexes of abbreviations aren't very searchable) but it took maximum zoom to see it. Argh.

If they got it right, I'll take back the last fifty nasty things I said about Mattel and/or Barbie in general.
