Reader Tom within 24 hours solved the mystery of the Monogram in my Christmas card. It was designed by Paul Lewis for Paul Burty Haviland (link*) (1880-1950) the son and heir of the french china manufacturer Haviland & Co. in Limoges Charles Edward Haviland and Madeleine Burty.
He was an early 19th century photographer and close of friend Alfred Stieglitz (1864-1946), and married to Renée Lalique's daughter Suzanne Lalique (1892-1989), the famous french Art Nouveau Glass designer.
Suzanne was an artist too and besides a creative artist and painter she created besides her own a marriage between the Haviland Limoges china porcelain and Lalique's artist-icy. Just "dots and open space" but: Beautiful !
