Arthur Lazenby Liberty addresses the Applied Art Section of the Society for the Encouragement of Arts, Manufacturers, and Commerce in London on May 17th 1904. Here he expresses with quotations from and attributed to Welch his thoughts on the history of Pewter. He later in the talk gives his thoughts regarding Liberty manufacture of Pewterware. He comments on the silver content of early tin giving pewterware its unusual warmth and appearance - which has since been shown to be incorrect. It appears he did not in this talk at least associate his celtic design theme with that of the Art Nouveau of Germany.
Indeed the chairman of the meeting in his final words expresses the view of the time amongst those concerned with antiquities concerning Art Nouveau which is not complementary.
