Hertfordshire uk

I see something on your rock art but the way the pictures are wrong. in my youtube videos Ancient Rock Art, i discovered they put paint marks on them. as it seems you have on yours it seems like.
So where the paint marks are hold with your fingers and look at it in different ways. Hertfordshire has history of Mesolithic and Neolithic 4,0000 BC .
Hertford came from Anglo Saxon 1011 it is now 2020.

Thank for that information I ddint no that about Hertfordshire i am new to collecting rocks . I found a face looking up at me a year ago in my back garden when I was digging fish pond. Then realising there were everywere in leveaaden green watford Hertfordshire.
I love collecting and learning about it thanks
