Stampless printed 'On His Majesty's Service' official cover with fine strike of OETA EEF RAFA skeleton cds dated 13 AP 1920. Addressed to 'Secret, Headquarters 3rd (L) Division, Bir Salem' with R.M.S. I.E.F. transit cds and Indian 'F.P.O. No. 79' arrival cds of the 3rd Division H.Q. at Bir Salem on reverse. A superb cover with an excellent strike of arguably the rarest Palestinian cancellation of the small Arab village of Rafa located on the border with Egypt which only operated between February 1920 and May 1921.
