I don't think it is. Could be wrong, but i tried to match moles. and they don't match. On Mia from femjoy, there is a mole on her stomach, and on the side of "her right" boob. I scanned through the Michaela Fenclova thread and although they look alike, she is missing the moles i just described. I think Mia and Michaela Fenclova are 2 different girls.
have pics from diffrent sets at M&B from 2003 but similar poses. sometimes you can see the moles, sometimes not. think its some kind of makeup that you cant see the moles. she is realy Michaela Fenclova aka Misha Elmer http://www.sportyone.com/servlets/firebolt?object=164704
