These first-batch cakes have been preserved in dry storage. One features the small rectangular Zhong character, re-wrapped by collectors in earlier years for protection and fitted with additional labels. The 7572 blend was produced only briefly in the mid-1970s, using Menghai grade 7 large leaves and without artificial fermentation.
