Who is this fashion artist from 1967 perhaps in Vogue magazine?

I would like to identify the artist of the following work of art from 1967:



Here is a close up of the signature, I'm having trouble reading it, perhaps it says Peters?:



I was told that the artist was perhaps from England and that they worked in fashion, providing sketches for magazines like Vogue. I was also told they were a peer of Dagmar Freuchen-Gale.

Thanks!
