In 2001 Anthony von Mandl, proprietor of Mission Hill Winery in Kelowna, B.C. Canada comissioned A.J. Rogac to create a special keystone for the winery's new home. The stone was to be placed in the set of contemporary, curved arches visitors pass under to enter the main winery grounds.

Hand chiselled from a five tonne block of Indiana limestone by A.J. Rogac Ltd., the keystone features images taken from the von Mandl family crest.

As the Mission Hill website puts it "For proprietor von Mandl, the keystone embodies the coming together of tradition, quality, heritage and innovation."

The keystone was installed into the arches at Mission Hill in August 2002 and officially unveiled during a gala celebration in September of that same year.
