That adds to the case a little
as I posted that piece in a separate thread and got:
Quote from: http://www.pressglas-korrespondenz.de/aktuelles/pdf/pk-2006-1w-bateman-vase-markhbeinn.pdf
Blumenvase „Fächer“ Nr. 4928
grünblaues Berylglas, Entwurf Lotte P. Moser 1925
Ludwig Moser & Söhne, Karlovy Vary [Karlsbad], 1928
aus Mergl 1997, S. 122
The auction states:
Böhmen, Karlsbad, Moser, Lotte P. Moserová 1925, 1950–1975. This data is repeated elsewhere.
Notice that Lotte P. Moserová (b. 1897) was the daughter Rudolf Moser so the designer name in PK is correct... What is puzzling are the 1928 and 1925 dates, does 25 refer to design date at 28 production? Clearly this vase was in production by 1929 and what is the significance of 1950-75. Manufactured again? She had relocated to France just before WW2 and stayed there.
