2d Blue (plate 1) on dated piece from Drogheda to the Stamp Office in Dublin. September 18th 1840 tied by 5 bright vivid red MXs of Drogheda. This cross is illustrated in Rockoff and Jackson Volume 2 page 324 on a 1d black cover. One can only speculate as to why the postmaster/mistress decided to cancel the stamp in such dramatic fashion!
