Conjoined twins sitting on a suitcase. From Succubus series.
A succubus is a female demon that has sex with men in their sleep. The male version is an incubus. They arise from medieval christian demonology and the first mention of a succubus is in the 1300s. They have sexual intercourse with their victims in order to possess their bodies. Lilith, the supposed first wife of Adam was said to be the first succubus.
The artwork was produced long time before Photoshop. Alva uses a technique that involved using card in front of the lens and shooting one half then the other on the same frame of 35mm film.
Artwork is ready to hang.
