In this progress proof the rooks are larger and clearer than in previous proofs. The ploughman’s legs have been clearly defined and there is a new shadow in the foreground. The trees have greater definition. Heysen owned a progress proof of Spring (Shirley 7 h) and remarked: ‘I am particularly impressed with “Spring” … – of course I love them all – for each has its own particular merits ... Spring – I have always thought a particularly lovely & happy thing’ (Heysen 1947).
