For Sunset Ridge Church in San Antonio, Texas, its century-old Tiffany Studios altar window was a mixed blessed. The dappled forest scene of far-off mountains, lush foliage, and flowing waters was a source of pride that illuminated the chapel with iridescent light. But it was also an insurance liability—so much so that for the past decade, Mountain Landscape (Root Memorial Window) (1917) was roped off from visitors. The church was keen for the Tiffany to find a new home and though private collectors and dealers were circling, it wanted a large public audience for the more than nine-foot-tall window. In May last year, the Crystal Bridges Museum of American Art in Bentonville, Arkansas, announced it had acquired the window for an undisclosed price (a slightly larger 1913 window sold at Sotheby’s in 2025 for a record $12.4 million).
