Whose finger is this?
Points to public art on tree
Community art:)

A delightful meet up for lunch and a chin wag after way tooooooooo long a time inbetween wagging...Nanna K showed me one of several sporadic pieces of art she and a fellow sleuth blipper have hung around their neighborhood.... The piece you see hanging on the tree is one of K's pictures.
Since it's kind of a secret project I won't say anymore other than I'm going to copy the idea around some of my neighborhood!  
  Extra is for blippe MMNaylor from her neighborhood
