I've seen this model in other GHM publications before, but as of yet I've not been unable to identify this model with the big hair and big bush! For reference this shot comes from the GHM publication Nature's Intention Vol.1 No.1 'A Series of Natural Art Studies' It was a 64 page medium format (8" x 10", 200mm x 250mm) magazine published around 1969 by Roydock books Ltd if that helps? She also appeared in single shots through-out Kamera at the same time and in Magnificent Models No.2 by Nostalgia Publications. Two more smaller shots below.
I've also created an 'Unknown Models' page to list all of the unknown models I come across, so that you can hopefully help me identify these mysterious beauties? There is also a link to the page on the right hand side under Models.
