This lot, featuring typical 1970s packaging, has been preserved in mild dry storage. The wrappers remain intact, made of thin patterned paper printed with the large rectangular Zhong character, hand-stamped with a green logo, and embedded with fine-print inner tickets. Crafted from grade 4 tea leaves and scattered with delicate buds across the surface, this version represents one of the earliest 7542 blends, produced just before full standardisation. The tea has developed a refined aged aroma with a lingering sweetness on the finish.
