The centerpieces at this year’s 30th Annual Penland Benefit Auction were not simply festive and unique—they were also fully functional! Glass artist Sally Prasch constructed over forty elaborate glass horns, each with a glass rainstick to accompany it. In this photo, a group of auction volunteers gives some horns a celebratory toot that could be heard all across campus.

Lots more photos are now up from auction weekend. View the entire auction slideshow here.
