Ornately engraved and decorated with cast brass wreaths, ribbons, and a natural horn extending through a lyre, the mammoth "Holtonphone" was the company's largest Sousaphone model. The bell decoration features a large elk head with 12-point antlers. The 58-inch-tall, model 130 Sousaphone with a 30" bell was marketed in Holton's 1935 catalog as the "Revelation BB-flat mammoth Holtonphone, the size recommended for both band and orchestra."
The article also explains that this historic Sousaphone was donated to the National Music Museum (along with a lot of other stuff) in 2008, marking the 110th anniversary of the founding of the Holton Company.
