The postcard shows the Philippine dance Jotabal, performed by the Far Eastern University Dance Troupe. Jotabal is a lively festival dance in Camohaguin, Gumaca, Quezon. It is derived from the words Jota and valse (means waltz, a step or a dance in three-four time). The male wears Barong Tagalog and black trousers and female wears Maria Clara dress.
I was not able to find the history of the dance.
