Trewern menhir

After seeing these wonderful photo's of the carvings at Boscawen Un [http://tom.goskar.com/2015/09/14/neolithic-breton-style-rock-art-at-boscawen-un-stone-circle/] I had a look with these carvings in mind at Trewern standing stone [SW432321], and low and behold on it's North Western side there is very very clear manmade carved breton-style "breasts", They are identical to the clearest one at Boscawen Un, But this time there is one above the other not side by side, Between them but to the West [making a triangle] is another "cup" with a little "breast" inside it and a ring around it [all shown by the purple arrows in the photo], The North East side also has "something" breastlike, But larger and lower, The light was wrong on this side for photo's though.
