The design difference between Spring-Autumn and Han Dynasty jade tiger plaques

The jade tiger plaques in the Spring-Autumn period are carved with symmetrical motifs on both sides of the jade tiger plaques while those of the Han Dynasty are carved with different motifs on each side. In terms of artistic design, the jade tiger plaques of the Spring-Autumn period are a two-dimensional presentation while the Han Dynasty jade tiger plaques are a three-dimensional presentation. (The one on the left and the one below are the Han Dynasty jade tiger plaques from The National Palace Museum, and the bottom left is the jade tiger plaque of the Spring-Autumn period from The Palaceantique Collection USA).
