BOMB DAMAGE. 1979 envelope that was in a Post Office in Birmingham when an I.R.A. bomb exploded damaging the letter. A Postmasters label expressing regret that the mail has been damaged has ‘BOMB DAMAGE’ in manuscript. Although there is no datestamp, the handwriting of ‘BOMB DAMAGE’ is clearly the same as other similar damaged covers. Thirteen letter bombs either exploded or were defused at post offices in Birmingham during the latter part of June or early July. A scarce item from these I.R.A. terror attacks.
