Golden puzzle

While having coffee round the table with our friends P and A, we admired the jigsaw that P had just completed. It is a very golden view of the dome of St Peter’s Basilica in Rome and was one of the fifty golden gifts that four of us gave to P and A on the occasion of their golden wedding anniversary last year. P loves doing jigsaws and she says that this is one of the most difficult she has ever done. She never looks at the picture on the box once she has started a jigsaw so I can see why she found this one particularly testing.
