Where do you see paintings by Ruskin Spear (1911–90)? In the salerooms mostly, because his work in public collections is rarely on display. Until the National Portrait Gallery closed for redevelopment it was, however, possible to study Spear’s splendid portrait of ‘Citizen James’ (Sid James) peering from a black and white TV screen, and his oil sketch of Harold Wilson wreathed in pipe smoke, the epitome of political cunning.
