Old Taiwanese beer mug From Kinmen

This vintage beer mug, dating from the 1970s, is inscribed with "Yongsheng General Store" and originates from "Yongfeng Trading Co.," the predecessor of Kinmen's earliest food distributor. "Yongfeng Trading Co." has been in operation since 1959 (Republic of China Year 48) and is located in Jincheng Township, Kinmen. During the military administration period of Kinmen, it operated for over six decades, evolving from selling various food supplies to becoming a major distributor, making it a well-known store in Kinmen at that time. The triangular mark on the bottom indicates that the mug was manufactured by a Taiwanese glass factory, with the number representing the mold number. This beer mug is a vintage item and shows signs of use. Please refrain from purchasing if you mind these signs of wear.
