Thanks, luv, for posting this link... I noticed Connie's comment (I think I must have missed it originally) and went back to look.
The way you showed the "sculpting" of Grayson/Peggy's back bears a strong resemblance to a symbol commonly used today by Witches and Neo Pagans for the Great Goddess in Her aspect as the "Triple Goddess," specifically with lunar associations--the two back-to-back C's (often drawn with a circle in the middle) are signs for the waxing and waning Moon.
Pure serendipity, but, given that some of us routinely refer to GH as "the Divine One," don't you think?
