Helen that is an amazing level of detail.
Julien Viard bottles ( I looked it up) were made by Baccarat, Depinoix, Maugenest, Pochet et du Courval, Bobin and Sté Parisienne de Verreries - so the confusion regarding the producer still rules. But at least designer and approx dates have now surfaced.
A grand entrance to the G M B - thank you so much and welcome.
