Developed in 1868 by Simon Viollet who registered the brand name in 1873, Byrrh opened its factory in Thuir in 1892. In those days, when the aperitif hour was an almost sacrosanct ceremony, this type of fortified wine was very fashionable. Jules-Alexandre Grun (25 May 1868 – 15 February 1934) was a French post-impressionist painter, poster artist, and illustrator.[1] Grun's best known painting is called The Dinner Party, produced in 1911. It was, however, in the fields of poster art and illustration art, for which he was famous. He was employed at a large printing company in Paris and his artistic director was Jules Cheret. Cheret was also his main competitor in poster art. (Wiki) This poster is published in Grun Posters by Israel Perry and Alain Weill 2005 page 116
