The "Ardatov Type" stamp is the philatelic name for the fifth design type used by EZGB to issue zemstvo postage stamps starting in 1902. According to published sources, the name was assigned after Ardatovsky Uyezd, for which stamp printing first employed this design.
In 1913, the zemstvo post of Konstantinograd Uyezd (Poltava Governorate) was opened. Mail was sent from the uyezd administrative center, the town of Konstantinograd (now Krasnohrad), to 16 locations within the uyezd. To pay for the delivery of private correspondence, zemstvo postage stamps denominated 1, 2, 3, 6, 10, and 30 kopecks were used. They were printed in a private printing house and at EZGB. All stamps depict the uyezd coat of arms. The stamps were cancelled with a round date stamp.
