Since 1972, the Horns have been cultivating one of the most significant collections in Western Australia. While the quality of the work in the collection is outstanding, the collection is particularly notable for its focus: West Australian art.
Artists include Kelsey Ashe, Philip Berry, Tom Gibbons, Akio Makigawa, Paul Moncrieff, Miriam Stannage, Jon Tarry, Valerie Tring and Trevor Vickers.
