The flag is a classic flag of the Sultanate of Sulu, the owner of it is Mr. Edwin Bautista, a Filipino collector and researcher.
Captured Sulu Sultanate Flag. 24.5" x 18.75". Linen, with hoist, blue canton with five stars, cross dagger and spear, and other device separately applied. An old typed note attached to the flag reads "Phillipine [sic] Insurrection Flag Captured at San Pedro Masantry on day General Lawton Was Killed". This flag was brought back by Captain Lucien G. Berry, Assistant Adjutant-General of US Volunteers. The flag must have been captured on December 19, 1899 (the date of General Lawton's death) in some unspecified action against the insurgents around San Pedro. Capt. Berry, a West Point graduate, brought back several interesting war souvenirs from his service in the Philippines.
The flag is kept in a private collection: The Flag Center/ Zaricor flag Collection.
