Dr Stanley Kronenberg was one of the foremost authorities on Polish philately. Included on our website we proudly present pages from his extensive collection and research. Included in this collection are extensive studies of forgeries and the identifying characteristics of these fakes. Many of the items shown are important reference items for specialists in Polish philately. Of particular note, we have presented his collection of the Second Warsaw Provisional issue, overprints of the “Karlfund” stamps (“Lublin Issue”), the first and second (“Gniezno”) Poznan issues and their forgeries, and the Kraków Issue forged overprints. Pictured above is the famous 1944 Husarz Karnet from the Gross Born Officers POW Camp.
Polonus would like to thank Hank Bieniecki for his work in preserving Dr. Kronenberg’s collection. After Dr. Kronenberg’s death in 2000, Dr. Kronenberg’s wife, Eva, approached Hank to discuss how to best preserve a record of his collection. Hank suggested to digitize the collection and worked to acquire the necessary equipment. He taught Eva how to scan the collection with the result of what you see here today. It should be noted that Dr. Kronenberg never allowed a computer in his home prior to his death!
