Thirteen years ago Donna Lennard and Alberto Avalle took over what was then the studio and workshop of artist Warren Muller and opened an antiques store with Muller’s quirky chandeliers front and center. It would become the little slice of loveliness known as Il Buco, where Muller’s creations are still for sale at prices starting around $3,000. You’re likely to get the owners to part with the one incorporating oil cans — Lennard says customers always bang their heads on it — but if your heart is set on the not-for-sale one above the bar (an antique rake with porcelain sockets on each rung, not pictured) Lennard will send you to the artist’s Philadelphia studio. “He’s a magical guy,” Lennard says of Muller. “He loves to play with light in fantastical ways.” So fantastical, in fact, that Muller, who now sells larger pieces made from Mini Coopers and the like for as much as $200,000, is hard-pressed to describe his creative process. Nevertheless, we asked him to try.
