Throughout the time spent working at Labbett House, East Challow, Gus opened the Studio for Oxfordshire Art Week and for a Winter pre- Christmas Show. He also participated in a range of group shows as well as solo exhibitions further afield. His style and approach were in great demand at Adult classes and for Art Society Demonstrations.
In 2004 Gus entered the Sunday Mail’s ‘Not the Turner Prize’ competition. In May 2005, ‘The Gus Mills Gallery’, opened in Wantage. Set in a beautiful and very old building, it allowed Gus the opportunity to work alongside the ceramics, glass and wood of many other artists. The Gallery enjoyed over three years of success until changes in Wantage and the economic climate forced closure. For a few years Gus combined several days a week at the Oxford Castle Market with working once again at the Attic Studio, East Challow. Currently he takes part three times a year in a prestigious Art and Craft Market in Broad Street, Oxford and this has led to a wide collection of work focusing on Oxford and particularly the college buildings. He has recently begun selling his work in Blackwell’s Art and Poster Shop. He continues to share his watercolour talent with young artists through work in schools and is available at the studio in Challow, where by arrangement paintings can always be viewed, as well as discussing commissions.
