1911 KEVII 1/2a Envelope uprated 1/2a to London, endorsed "Aerial Post" and cancelled by the "FIRST AERIAL POST / 1911 / U.P EXHIBITION ALLAHABAD" handstamp in violet, a further strike on the reverse in black, also backstamped with the Allahabad c.d.s (Feb 18), a London arrival machine on the front. Opening tears at upper edge and both sides, rather crudely repaired with three large hinges mainly on the reverse (all clear of the Aerial Post backstamp), still an unusual and rare example of this handstamp in black ink, only used in that colour on a small number of V.I.P mail items. With R.P.S certificate (2012). Photo on Page 180. (Image1)
