Light Brocade was a "beautiful"[2] brown mare bred in England by her owner John Lambton, 5th Earl of Durham.
Light Brocade's dam Trilogy was a sister to the Ascot Gold Cup winners Trimdon and Foxhunter and a high-class racehorse in her own right, finishing second in the 1000 Guineas in 1926.
[6] Light Brocade made her first appearance of 1934 in the Column Produce Stakes at Newmarket in April and came home last of the seven runners behind the Jack Jarvis-trained Campanula.
[2] On her only other appearance, Light Brocade was brought back in distance and assigned top weight for the Coronation Stakes over one mile at Royal Ascot in June.
[8] In the official Free Handicap for 1933, Light Brocade was rated the second best two-year-old filly in England, one pound behind Campanula.
