Wedgwood hoped to monopolize the aristocratic market and thus win for his wares a special social "cachet" which would filter to all classes of society. Wedgwood fully realised the value of such a lead and made the most of it by giving his pottery the name of its patron: Queensware, Royal Pattern, Russian pattern, Bedford, Oxford and Chetwynd vases for instance. Whether they owned the original or merely possessed a Wedgwood copy mattered little to Wedgwood's customers. In 1773 they published the first "Ornamental Catalogue", an illustrated catalogue of shapes. A plaque, in Wedgwood's blue pottery style, marking the site of his London showrooms between 1774 and 1795 in Wedgwood Mews, is located at 12, Greek Street, London, W1.
