This jarlet, declared a National Cultural Treasure, is the earliest pot recovered in the country. It has a distinct rim that resembles a shouting or yawning person, hence the name.

Discovered by Dr. Robert Fox in Leta-Leta Cave, northern Palawan in 1965, this jarlet is associated with the Late Neolithic period (approximately 1000 to 1500 BC). It was excavated in a burial site where a stone adze, as well as other intact pieces of pottery, including a stem cup and a footed jarlet, both of which are also declared national cultural treasures, were recovered. -source https://bit.ly/3WLCxDn
