Thomas Cardoza's excellent site http://www.cantinieres.com/ and his book Intrepid Women: Cantinières and Vivandières of the French Army document the the history of French Cantinieres up to World War One. He records the final years of the cantinieres and the increasing regulations making it hard for women to make a living as cantinieres. The wagon style and size used by these women was regulated and thanks to early 1900s postcards, we can see these wagons and the staff attached to to the cantinere when the army was on maneuvers. You can also see the lack of the cantiniere costume in these photos. I found these cards on various on-line auction sites.
