Gisele Bundchen retired from modeling earlier this year, but she still has so many fans out there that a $700 book celebrating her career was sold out before it could get anywhere near bookstores. Only 1,000 copies of the 536-page book, which features more than 300 photos from her 20-year career, were printed and they were all spoken for by the time a release party was held on Friday, reports US Weekly. A source tells People that both the publisher and the Brazilian supermodel were stunned by the success. "Everybody thought, given the price point, that it would be a different scenario," the source says. "They were getting ready to promote it." All proceeds will go to charity.
