interesting article on the AVG - the Flying Tigers and the nose art on their P 40 Curtis fighters. seems like the British copied the shark mouth from the Germans (used on an inferior fighter) and the Tigers took it from the Brits:
. . . Although the Flying Tigers made famous the shark mouth nose-art design,
the RAF had been the first to popularize it during World War II. The RAF 112 fighter group was referred to as the “shark” squadron because its planes sported the shark mouth design.12
It is interesting to note that the RAF had taken the shark mouth design from the Germans who during World War II were the first to adopt the shark mouth design on their Bf 110s of II/ZG 76. Years earlier, in World War I, the German Roland C.II Walfisch had a whale mouth design similar to the shark mouth design. Other than in a few air shows where individuals painted their own plane s, the shark mouth design remained unused until World War II when Germanybrought it back. As it turned out, the Bf 110s with their shark mouth adornments were not especially good planes, and the RAF took the German design and used it against them. . . . The Walt Disney studio was commissioned to design an emblem for the AVG and the result was a tiger with wasp-like wings flying out from a “V” for victory.. . . Chinese symbolism goes a long way in explaining why the AVG’s name was the Flying Tigers and not the Flying Dragons. Initially, members of the China Defense Supplies wanted a dragon emblem, which seems the obvious choice because a dragon commonly represents China. In Chinese mythology, a dragon is not fat and evil as it is in European mythology, but skinny, snakelike, and benevolent. It spends its time in the sea as much as in the air and is a symbol of imperial power.17 The tiger is also revered in Chinese mythology, but for several reasons is more fitting than a dragon as a nickname and insignia for warplanes and pilots. First, the AVG fought in southern China and Southeast Asia where tigers were commonly found. Second, the tiger is considered the king of land animals and a model for courage and ferocity. Third, tigers symbolize military strength, and images of tigers used to be painted on shields and forts to scare the enemy. -
