George Elliott put an anchor sign on the work he produced whilst working at his studio in Bewdley, Worcestershire. Bewdley used to be a major inland port, many centuries ago, and there is an anchor on the town crest.
The work that he produced after leaving Bewdley won't have the anchor. Although he may have remembered his seafaring days with affection, the anchor was there as a nod towards Bewdley's history.
Incidentally, in the Middle Ages, a nearby city would sometimes be referred to as "Birmingham near Bewdley". Bewdley was important, then.
