Roberts was in the habit of giving presents of his work to family & friends at Christmas, and the ‘Dec 25’ date indicates that this was a Christmas gift. Some works he gave were made specially but many were existing sketches or oils.
It’s likely that this watercolour was made some time before Dec 1843 and would have been undated until given as a present. It may have been a sketch of an idea for a vignette or an alternative that wasn’t used in his folios.
