Two single weight airmail covers to Germany, sent in May and November 1968, and one to the UK, sent November 29, 1968. Franked with a combinations of 1968 commemoratve issues, or the 10c Jack Pine Centennial and the John McCrae issue, to make up the 15c rate. The UK cover is a little ratty, but has an interesting black boxed "Canada Port Paye" handstamp on the front.
Est $10.
