Frugal or Beautiful?

Norman Haddow tells the story of a time he had to do an evaluation for the DSWA of two walls built either side of an entrance way by two different wallers, both named Charlie. 


The farmer who owned the property came down the lane to talk and when Norman explained what he was doing the farmer asked him which he liked better.
"I like Charlie M's wall." Norman replied. 
"Well I prefer Charlie R's wall" said the old farmer, " because he came afterwards and built a perfectly good wall with all the leftover stones that Charlie M. couldn't use."


See if you can decide whose wall this is in the picture?
