These are COPIES of actual Avro CF-105 Avro Arrow Aircraft invitations to a) The unveiling Oct. 04 1957 and b) buffet + cocktails afterward at the Queen Elizabeth building.  The originals would have been tipped into documents for certain privileged people in Government.  Each is approx. 3 1/2" X 4 3/4".  There are also two MINT NEVER HINGED 50's stamps, one 1959 stamp commemorates the ARROW and the SILVER DART.
