The fantastic photo is not from my collection (sadly) but I found it on the Retrospace blog, located here. The page is from a 1969 cover article on Nichelle that features many good pics! But this one can't be beat for sheer awesomeness.TOTALLY agree. There isn't even a measuring system on earth capable of calculating this awesomeness of Nichelle in this photo. Nichelle conquers the world!!
