This is a vintage white-porcelain Cleopatra tiki mug with a very light lime tint, manufactured by Porcelanas Pavón for the Bora Bora tiki bar. The design features a detailed bust of the Egyptian queen Cleopatra wearing a headdress and collar, with "Bora Bora" written in a stylized font across the front of the flared base.

This specific mug design is adapted from a vintage Spanish liqueur bottle ("Licor de Sinuhé" by Destilerías Soriano), produced here as a bottom-solid cocktail vessel without the original metal screw-base.
