This is another “Winsch-back imitator”, but already with the same “Correspondence” and “Address” imprint as above. Between POST and CARD you see a capital ‘D’ with arrow by a yet unidentified publisher. Furthermore the Christmas card shows a series as well as card number imprint. Postally used in 1913. No “Printed in Germany” nor “Made in U.S.A.” imprint. Printing quality of address side is average, picture side okay = common chromolithography, oval border embossed. One of a number of other cards showing a Winsch back-type like address side layouts.
Another publisher who very likely tried to benefit from the well introduced design is found on next page.
Together with a list of potential German printers who could had been the printing source.
