Heraldic panels were made of either stone or bronze and, in some cases, brass. These panels were, and still must be, displayed at the main entrance to the field; the Lion panel to be fixed on the left of the entrance and the Unicorn panel on the right, except Scotland, where the opposite is compulsory. Where the piers of the entrance are of brick or stone, the panels were of stone high by broad. Where wooden posts form the gate-supports, smaller plaques in bronze were issued – 11¼ins high by 8¼ins broad.
