This macabre specimen is well suited for scientific display in a curiosity cabinet or part of a gothic decor. It measures 7" tall with the base, and 4" front to back.

Ronnie and Donnie Galyon are the world's oldest living set of conjoined twins and also the world's only adult male conjoined twins. Born in Dayton, Ohio on October 28, 1951, the brothers, joined from the sternum to the groin, were delivered vaginally. According to Ward Hall, the twins' mother rejected them when they were born, leaving them to be raised by their father, Wesley, and later stepmother Mary. Because they share a single set of male organs, doctors decided not to separate them.
