In terms of Australian art, he was a pioneer of this kind of activity, and his presence in Adelaide and at the Contemporary Art Society had an osmotic effect on a later generation of painters who emerged from the South Australian School of Art and are now credited with bringing Hard Edge, Colour Field and Op Art to the fore in Australian art. Sádlo was also a pioneer of Pop Art in Australia, and used collage extensively in some of his work from the 1960s, councurrent with a second-wave of Australian collage artists (after the 1940s’ surrealists), such as the Annandale Imitation Realists. Sádlo was also a pioneer of modern enamelling and jewellery in Adelaide, and his influence has been recognised on a later generation of successful jewellers in Australia.

He has lived in London since the early 1970s, and has represented Britain at 4th Biennale International del ’Art de l’Email, Limoges, France (1976); the 13th Exhibition of International Enamelling Art, Ueno Royal Museum, Tokyo (1979); at the 5th Limoges Biennale (1980); and won the pize for enamel picture at the International Exhibition, Ueno Royal Museum, Tokyo (1987). he has also exhibited at 3 Internationales St Gallener Festival der Kuenste in Austria and held major survey exhibitions in Buckinghamshire, UK (1997) and Zapadoceska Gallery, Plzen, Czech Republic (2006).

He is represented by Henry Paddon Contemporary Art in Eastbourne, UK, and his reproductions are available online through Sadlo Art Limited: http://www.sadloart.com
