Julie London told Life Magazine in 1957 that she had only a thimbleful of a voice, and I have to use it close to the microphone. But it is a kind of over-smoked voice, and it automatically sounds intimate. Her vocal style has been described as being sultry, sexy, come-hither, intimate, breathy, warm, smoky, haunting, husky, sullen, sad, suggestive and seductive.
The majority of her album covers were graced by sultry, yet sophisticated pictures of Julie - the cover of her first album, Julie is Her Name, being, at the time, thought of as so sexy that it was described as ...generating enough voltage to light up a theater marquee. The album Calendar Girl is graced with 12 cheesecake photos of Miss London - one for each month of the year, with an additional large photo for the thirteenth month on the inside of the foldout cover.
