Elizabeth Taylor's unpublished love letters up for auction

(CBS/AP) CONCORD, N.H. - Last week, it was announced that an Andy Warhol portrait of Elizabeth Taylor was heading to the auction block. Now, it's the late actress' unpublished love letters that will be up for sale.

One note, in which the 17-year-old Taylor tells her first fiance that she'll "never love anyone else - period" is among more than 60 of her unpublished love letters being put up for auction in New Hampshire.

RR Auction in Amherst bought the letters two years ago from William Pawley, who was engaged to Taylor for less than a year in 1949. Officials had estimated they were worth about $25,000 before Taylor's death last week and expect them now to fetch two or three times that at the online auction in May.

Taylor didn't just profess what she described as her perfect, complete and mature love for Pawley. The starlet also described studio life, including the filming of "A Place in the Sun."

The Oscar-winner, who died Wednesday at age 79, went on to marry eight times - including twice to actor Richard Burton.
