Jose Rizal was featured on the 6s definitive and official stamps issued on June 19, 1964 wearing the traditional "Barong Tagalog" shirt. Although Rizal was a Filipino nationalist, there are no photographs of him wearing a barong. However Rizal appreciated indigenous clothing and textiles, and donated his collection to the Ethnological Museum of Berlin in 1887. Among the artifacts was a barong tagalog, but no evidence that it had ever been worn by Rizal.
