"Huile Lesieur" (1924) by Henri Le Monnier
One of the great masters of stone lithography, his images can be found promoting products such as Perrier water, olive oil, fine butter and of course the chef riding the pig while selling ham. A great sense of humor and detail was used in creating his images. Most of Le Monnier's work was done post WW1 in the great printing days that encompassed the art deco period.
