 Under Moore's influence, Gladstone began a long period of experimentation with figurative work.In 1967, Gladstone received three commissions for Montreal's Expo 67, but several years later he was struggling to find work.There was an exhibition of his mid- to late-career plastic cube sculptures and his "Downtown Nudes Series" - a collection of oils on canvas - at the opening exhibition of Toronto's St. Lawrence Centre for the Arts, and in 1973 he produced the "Electric Figure Series", another collection of oils on canvas.
