A tree well framed by the London Eye,London,SE1.I had just delivered a package to the Shell building,a Mr.Caufield,if my memory serves me right.I remember that as we discussed my favorite topic,Hadrian's Wall,as Mr.Caufield's surname,is the same as the modern title of Hadrian's Wall milecastle no.42,i.e.Cawfields.I came outside and saw the tree within the wheel,took out my camera and hey presto,the rest is history.
