There are a few weird things about top model Cindy Crawford. Things that set her apart from the other "cover girls." She was born in the United States. She doesn't want to be an actress. Her boyfriend isn't a rock star. The weirdest thing of all, though, is that she has brown eyes.

Vogue Magazine, with a mind of its own, put Crawford on its cover last August after she had been rejected elsewhere. "I worked for Harper's Bazaar first and they didn't like the way I looked," she says. It could have been any number of things, she supposes, the brown hair, the brown eyes, the mole at the corner of her lip. "I am the only brown-eyed girl {Vogue} used on a cover," says Crawford, "other than Shari Belafonte-Harper, who is black."

The other weird thing about Crawford is that she's hopelessly wholesome. Corn-fed and timid, she tends to bring her hometown of De Kalb, Ill. -- the town's logo is the "winged ear" of corn -- into the conversation.

Back in De Kalb when her mother got the news that her daughter's first TV commercial, for Revlon's "Intimate" fragrance, had been banned by NBC, she called up Crawford. "What did you do in it?" she asked.

"It didn't seem daring at the time," says Crawford. The ad, a spinoff of a scene in the movie "9 1/2 Weeks," is a silent, quick-paced spot during which Crawford is subjected to sizzling ice cube torture at the hands of the usual perfect-looking man. The steamy part comes when the ice cube drips down her de'colletage. The commercial ran here, in April and May, after 9 p.m. It's being brought back at Christmas.

Crawford, 21, began modeling at 17, she says, because she was sick of hoeing cornfields for summer jobs. She went to Northwestern University for a year on an academic scholarship and studied chemical engineering. She modeled in Chicago and Paris before moving to New York.

The success of her August Vogue cover -- it sold more copies than any other issue in 1986 -- led to two more Vogue covers, and those of French Elle, Mademoiselle and Self.

Harper's Bazaar, tail between its legs, tried several times to give Crawford another try, but to no avail. So how come Crawford's picture appears on its June cover? The photograph, by Rico Puhlmann, was taken a year ago. Crawford says, "They wouldn't have touched that picture with a ten-foot pole before Vogue used me."
