Hans Kohler & Co, Munich (H.K.& Co., M.)

The cards can be marked by various combinations of the “palette” logo, the initials “H.K.& Co M.” and the company name. The “palette” logo often appears in the stamp box where it can be hidden. In the last example for instance the legend on the cards is ‘Edition d/Art “Palette” G.m.b.H. Berlin. Evidently the company became a G.m.b.H at some point.
