Another important piece of work French created was in seven panels, The Legend of Sinbad the Sailor, in 1956. It hung in the Legend Cafe in Melbourne.
In 2009, Earth Creations was hung in the St John's College Chapel (St. Lucia, Brisbane) by the UQ Art Museum installation team, two years after being commissioned . The piece is a stacked triptych.
French's work has been the subject of more than 40 solo exhibitions in Australia, and been part of many group exhibitions outside Australia.
