I need a little help. You see I'm writing a book were everyone has a doppelganger, or double, and I need to get my head around the concept.
How I do this is either by reading stories pertaining to the subject or by looking at various pictures.
Please post any picture that has to deal with twins, doubles, doppelgangers, or two people who are completely opposite yet look alike.

Thank you so much for your help.
