Until a few decades ago, one of the most common souvenirs for the traveller was an item of crested ware. The ‘crest’ was the coat-of-arms of a Town or District printed onto a small white porcelain item. The item only infrequently had any connection with the town whose crest was displayed on it.
This web site shows a selection of crested items bearing the coats-of-arms of the three Boroughs that made up what is now the London Borough of Tower Hamlets.
