In 1916 Marinduque was part of the Province of Tayabas. On pages 3,4 and 5 of Alzona’s paper there is a discussion concerning Sinamay use in Marinduque and The Boac Terno. Sadly there are no illustrations in the paper.
From an October 1916 paper entitled “Activities of Women in the Province of Tayabas” by Encarnacion Alzona.
