Ancient cities, museums and nature with its climates and seasons were of key importance.

Kalkhof’s many mixed exhibitions included Galerie am Bohlweg, Braunschweig, 1962; University of East Anglia, Norwich, 1971; Towner Art Gallery, Eastbourne, 1972; British Painting ’74, Hayward Gallery, 1974; Camden Arts Centre, 1981; and The Seventies, Brixton Art Gallery, 1985.
