1915, Falkland Islands.
Registered "Wilson cover" to Birmingham, bearing 1/2d., 1d., 2d. and 2 1/2d, tied by double circle datestamp (Nov. 22, 1915) with Falklands registration label numbered "80" below. Backstamped transit oval "London-8 JA-16" and "Birmingham" same day. Very interesting and fine.
