I would like to find a relatively high resolution copy of the photograph used as a basis for this depiction.
I have only been able to find it referenced in out of print books and I am hesitant to purchase anything dead tree online as I do not know the contents or if this specific painting is even featured.
Images I have found online focus on other paintings in the caves, dancing rituals, fertility depictions, hunting resources and other standards.
: Ancient paintings of mushroom-ed humanoids dating to 5,000 B.C. have been found in caves on the Tassili plateau of Northern Algeria.
