Eusabius
Eusabius welcome , I tend to agree with Phil about the identity of this artist, the artist I remember always wore a macintosh (mac) as we used to call them plus a cap, I never seen him any different he always adopted a seated position, sitting with his knees folded underneath him . He had a Jack Russell type dog , the pictures were drawn on the flagstones in front of him , so you had to watch where you stepped, easier said than done. At the age of about 5 or 6 thereabouts , I inadvertently walked on one of the drawings and accidently stepped on his chalks , he went absolutely ballistic , it ended up a war of words between him and my mother . If memory serves I think the dog was named Judy.
