Perfection as a concept is a singular excellence, incapable of being duplicated or paralleled. Thank God that the world is a so much richer place than the arid plane of theoretical values. The rich reality is that we on this earth have at least once enjoyed double doses of perfection, one half of which is embodied by Madeleine Collinson. A simultaneously wholesome and exotic brunette, Madeleine is one half of the Collinson twins, a late 1960s and early 1970s phenomenon of mirror-image female fantasy bait, two sisters born minutes apart who enthralled legions of men around the globe with their October 1970 Playboy centerfold. Not ones to shy away from onscreen skin, this pair of stellar pairs can be seen dually cavorting in a string of three shocking skin relics from the Age of Aquarius. How can you tell Madeleine and sister Mary apart? Easy. Madeleine is the one who plays the vampire in the woefully misnamed Twins of Evil (1971).
