The website and advertisements for Four Season Gutter Protection feature four cartoon medieval foot soldiers wearing helmets and brandishing shields and weapons – flails (a type of mace) and spears or pikes. The heads of the weapons are in the shape of different leaves, and the leaves also feature on the soldiers helmets and shields. The soldiers are evidently protecting your gutters against leaves.
Four Season Gutter Protection are an Australian-wide company based in Victoria.
