1929 Registered airmail postcard to Belgium.

1929 registered, airmail postcard to Brussels, Belgiu, from Calgary, Alberta (JUN 16) with 11 stamps tied on postcard. Reverse with Montreal (20 JUN), Montreal B&F Div (Jun 20), and London, GB transit bs.

Clearly philatelic but registered postcards are rare, and an 11 colour franking quite spectacular for Canada.
