The 1939 rally never occurred due to the onset of war in September of 1939. These proof cards or test runs were done in a set of six and were never dated and printed off scrap paper bearing a landscape scene. This is the first time I have encountered these and they are referenced in Bender Vol.2 on pages 342-343. Very nice cards meant for the 39 Rally.
