"DISINFIZIERT" cachet (43 x 5.5 mm) in lilac probably used by the German Field Post in the Ukraine in April 1942.
Typically letters and cards of the First and Second World War were disinfected at a lazaret. The card does not mention a lazaret also the spelling "DISINFIZIERT" with "I" instead of an "E" (DESINFIZIERT) is odd for Germany. Otherwise Dr. Meyer is listing a similar cachet "Disinfiziert" in his book "DISINFECTED MAIL" on page 293 used by the German Field Post in Ukraine in March 1942.
Are there further examples known?
