British Antarctic Territory

Late presses today. Must have had equpment problem, I've still made my Monday deadline with 8 hours till deadline.
This is a nice cover, because it's #1 British Antartic territory. #2 Silver Jubilee issue. #3 It has a ship on it(albeit granted I can't deduce the ship as it's not mentioned much because the event depicted is the land crossing of Antarctica). What more do you want? OK it's an FDC also. That's #4.
