“Classic Holiday Treats,” like gingerbread men and sugared fruit, albeit extra large sized, adorn one of six fresh pines at the Carnegie Museum of Art.

PITTSBURGH — “Solid Gold: Classics That Endure” is the theme for this year's decorated trees at the Carnegie Museum of Art, the 50th year for the holiday tradition.

The six, 20-foot fresh pine trees in the Hall of Architecture are decorated with ornaments handmade by members and friends of the women's committee of the museum.

The live pines are available for viewing through Jan. 12. Neapolitan Presepio, the Italian Nativity scene, is on display through Jan. 8.

The trees highlight art, culture, and science. Included are the “King Midas and the Golden Touch” tree and the “Green Eggs and Ham” tree.

Another tree portrays “Tracking Nature Bird by Bird” and was decorated by the committee in conjunction with Carnegie Museum of Natural History, whose bird migration research program at Powdermill Reserve in Rector, Westmoreland County, is also celebrating its 50th anniversary.

A Teenie Harris tree, prepared by the docents at the Carnegie in collaboration with the women's committee, focuses on the work of the Pittsburgh photojournalist, who is featured in a major retrospective at the museum.

The Andy Warhol Museum and its Inner Circle Group have decorated a tree themed “Super Pop! Pow! Bang!” which celebrates comic book art.

A tree showcasing classic holiday treats was organized by the Carnegie Library of Pittsburgh special services department.In 1961, members of the women's committee decorated the first trees with the theme “Trees from Around the World.” Those trees were smaller in the early years, but when committee member B.G. Galey Alexander donated evergreens from her Ligonier-area property, they grew to their now standard towering height.Viewing the trees and Neapolitan Presepio is free with museum admission, which is $15 for adults, $12 for senior citizens, $11 for students with ID and children ages 3 to 18, and free for children younger than 3.Regular hours are 10 a.m. to 5 p.m. Tuesdays through Saturdays, extended to 8 p.m. Thursdays, and noon to 5 p.m. Sundays.The museum at 4400 Forbes Ave. will close at 3 p.m. Saturday and be closed Sunday for Christmas.
