Gunilla Lindblad has been a model since before your mother was born, or almost.
She arrived in Paris from Sweden in 1968, and soon after that, she would go to New York, where she became a favorite of legendary Vogue editor Diana Vreeland. In the seventies, Ms. Lindblad would come to personify the "haute hippie" look, a style that combined hippie culture with haute couture.
It was indicative of how the Merry Pranksters and the Deadheads would influence mainstream culture, though they probably weren't too thrilled with seeing their look get turned unto a commodity.
But if any model was going to legitimize it, it was definitely Gunilla Lindblad. :-)
She was represented in Paris by the Paris Planning and Elite agencies, appearing on Vogue covers as well as in Vogue editorials. She would be represented by the New York and Los Angeles offices of Elite as her modeling career progressed in the 1980s.
After fifty years as of this writing, Ms. Lindblad continues to model, and she is a client of Iconic Focus, an American modeling agency that specializes in veteran models, many of them famous names like Ms. Lindblad herself.
I ask you, does this look like a woman who has been modeling for half a century? Well, believe it. And believe this: Real beauty never fades, It improves with age, like a fine wine. Gunilla Lindblad certainly proves that in spades. :-)
