In addition to Lord Beaverbrook's own acquisitions, the Gallery had received two major donations of artworks before its opening. Toronto businessman James Boylen donated 22 paintings by Cornelius Krieghoff. Lady Dunn donated three portraits by Walter Sickert and three works by Salvador Dalí. Two of the Dalí paintings were portraits of Lord and Lady Dunn, while the third was the very large painting "Santiago El Grande", which was on display in the central gallery when the Beaverbrook Art Gallery opened and has become closely identified with the Gallery. This painting, which measures , and represents Spain's patron saint James the Great on a white horse, had been created for the Spanish Pavilion at the 1958 Brussels World's Fair.
