It’s an original work of the t-shirt design. I drew this with a calligraphy pen and used sumi and india ink on a small BFK rives HW paper. It’s a technique that many traditional stylists use in lion dance to make a fast cross-over movement to animate a lion’s head shaking and making it more lively, too. This performer uses a HK style lion with white ram fur. It’s popular in Hong Kong and China, especially in Zhou Jia Quan community.
