LOS ANGELES, April 23 (UPI) -- Matching play clothes worn by the seven Von Trapp children in the 1965 musical Sound of Music are going under the hammer at the end of the month.
The seven costumes, made from the drapes in Fraulein Maria's bedroom, are expected to fetch upwards of $800,000 at an April 30 auction by Nate D. Sanders auction house in Los Angeles.
The auction coincides with the classic movie's 50th anniversary.
"The costumes were worn by the children as they frolicked in the Salzburg Alps and sang the famous song 'Do-Re-Mi,' " a statement from the auction house said. "The creation of the play clothes provided an early pivotal point in the movie, as Christopher Plummer was captivated by Maria's creativity."
The costumes feature labels from Twentieth Century Fox and the Western Costume Company.
They last went up for auction more than two decades ago, though the Los Angeles Times reports a second set of the green matching clothes were sold for $1.56 million as part of a larger lot of Sound of Music costumes.
The company that conducted that auction in 2013, Profiles History, said that there are often multiple copies of the same clothes from movies.
