In 1930 B. Dondorf GmbH in Frankfurt produced an advertizing pack for Saks & Co, New York, also known as Saks Fifth Avenue. The name of the maker is not shown on the cards.
All court cards have Copyright in all countries by Saks & Company New York on one end. This is a so-called Forcolor pack, with the suit signs not just black and red, but in four colours to make them distinguishable better (green, black, red, orange).
There is a Joker coming with this pack, but this is missing in my copy.
