Greece resumed control over Epirus in November 1914; on the 30th, to meet the area's postal needs, stamps from its "Campaign issue" were issued with the overprint B. ΗΠΕΙΡΟΣ horizontally in black; red overprints were also made, but not issued. (Some cancelled copies are known to exist.) These replaced Epirus' definitive issues. In December 1915 the same overprint was applied vertically, reading either up or down, to Greek definitive stamps of 1911 and 1913 issues. All of these have been counterfeited.
