This is a woodblock printing block belonging to local company Lao Boon Seng (老文成). This block was used to print joss paper (commonly known as “kim zua” or “gold paper” in Hokkein).Joss paper is traditionally made from coarse bamboo paper and cut into individual squares or rectangles with a thin piece of foil attached at its center. Some versions will feature images of Chinese deities printed on the paper using woodblocks such as these.
