A fashion photographer, hoping to cash in on would-be parents’ wishes for a beautiful baby, is offering the eggs of eight models in an on-line auction set to start today. Infertility groups have expressed disgust at the offer, saying it turns human life into a commodity. But Cambridge, Mass.-based photographer Ron Harris says his offer is a reflection of American society, where beauty can be purchased by the highest bidder (who, as it happens, would be benefiting Harris financially). The website http://www.ronsangels.com has pictures of eight models who are offering their eggs for sale. The bids start at $15,000 and can go as high as $150,000. Harris said the site had already received a serious bid of $42,000.
