1922 Harrison 5-line Overprint on 1d horizontal strip w/join

1922 Harrison 5-line Overprint on 1d horizontal strip of 6 with join between stamps 2 and 3. The 2^nd and 5^th stamps each show a small accent over the second "n" in "héireann", proving that the overprinting stereo was 2 stamps wide. Very fresh unmounted mint with superb perfs, scarce as such.
