German Soldier Kurt Zierold & Kriegsjar and 50 similar items

(2) Two Antique Real Photo Postcards, circa 1915. Identified as Kurt (spelled Kwrt and Cowrt on the cards) Zierold. One image depicts Zierold alone in a studio portrait wearing his WWI era German uniform. The second image (with x at top marking him as the middle soldier in the top row) features him with the 105 Regiment, 5 Corp. The word "Kriegsjahr" is written in the sign identifying the group which I understand translates to "War Years" and denotes military service seniority and corresponds to a German soldier's pension eligibility. Divided backs, unused. Condition: These are original antique postcards, not a copy or reproduction. Please refer to the enlarged photos to inspect condition. Comments: These images originally came as part of a group lot of Zierold family photographs (all sold separately.) They include: "Uncle Kwrt, Cowrt or Kurt Zierold who served as a German Soldier during the WWI era (including two real photo postcards in uniform and a cabinet photo taken with his wife in a studio in Germany); their relatives Clara Zierold (high school style graduation portrait taken in Pittsburgh, Pennsylvania); and possibly Clara's sister Marie Zierold who was working in 1921 at the Westinghouse Air Brake Co. in Pittsburgh (three photos of Marie, one as a baby, one real photo postcard of her as a little girl with her doll; and a high school era graduation portrait. One provides her married name which is not decipherable, but starts with the letter "G"); and a cabinet photo of "Grandpa Zierold, Dad's Father" also taken in a Pittsburgh studio.
