Excerpt: "The Keystone Building, built in 1923, is one of two Stolp Island works by Elmslie. It is a relatively rare example of the Prairie style used for an office building. This style, noted for its horizontal emphasis and decorative applications, is typically found in houses rather than commercial office buildings."(Submitted on May 4, 2026, by Sean P.
