Although this card is artist signed, I'm sorry to say I haven't a clue who it is. The initials have been cut off but look to be O.H.W. However, the publisher marks verso "Egemes" with the funky M insignia in the stamp box are from the printing and publishing house of E.G. May of Frankfurt, Germany. (1878-1914)* Postmarked 1910, this illustrated postcard stands out among the crowd. At first glance, it's easy to mistake this for an M.M. Munk/Vienne card, but the lady is quite unique in her style and not the usual Vienne design at all. She's wearing rose arm bands and an ermine fur stole! No creases and any signs of age seem an insult to mention considering its age -- 104 years old! Any errant specks or spots appear to be inherent to the printing. The paper has a high-fiber content; matte. Size: 3.5 by 5.5 inches.
*Thanks to the Metropolitan Postcard Club of New York City for this information: The printing and publishing house of E.G. May was founded by the self taught lithographer Edward Gustave May in 1845. May was largely producing chromolithographic products by 1877 when he became heavily involved in the production of holiday cards. After retiring a year later his sons Robert and Franz took over the business and changed the companies name to E.G May & Sons. They went on to publish postcards but eventually switched to the tricolor process. When their logo was not used their cards were published under the name Egemes. In 1914 they merged with Dresdner Art Institute to become Art Institute May AG.
