E.D.E.S. produced three sets, only one of which saw postal use. The first two, a set of five (values 15, 25, 50, 100 and 200 drachmae) and a single stamp (1000 drachmae) inscribed Free Greece, were produced in 1943 and July 1944 respectively; all were imperforate. Almost all stamps from their second issue were confiscated by the occupying Germans. The third set, which unlike the others was perforated, was produced on July 23. Issued to commemorate two years of E.D.E.S.' existence, it consisted of four values (2000, 4000, 6000 and 8000 drachmae). It was not placed on sale until November 25, 1944. This date marked the second anniversary of the Resistance's destruction of the Gorgopotamos railway bridge. To commemorate that event, the third E.D.E.S. issue was overprinted with ΓΟΡΓΟΠΟΤΑΜΟΣ 25-11-1942 (Gorgopotamos 25-11-1942) and placed on sale for one day at the Ioannina post office with the condition that they would be attached to a cover.
