This sarong is decorated with a buketan (bouquet) design, set against a background of filler motifs. It is signed “Njonjah / Oeij Kok Sing” and stamped “Oeij Kok Sing / 10 Juni 1931”. Njonjah and Oeij are the historical Dutch spellings for Nyonya and Oey, a Chinese Indonesian surname of Hokkien origin. Nyonya Oeij Kok Sing was a second-generation batik maker in Pekalongan. She began to produce high quality batiks in the 1920s. Her batiks from the 1930s reveal great technical virtuosity and a creative use of colour, made possible by synthetic dyes from Europe. After the Second World War, her daughter Jane Hendromartono (1924–1988) took over the family batik business.
