Just to show them off, here are three covers I got today down in Toronto. All are addressed to Miss Grace Wilson of Boisetown NB. The collection I bought these out of were mostly addressed to Miss Wilson. There were some nice advertising cover, but unfortunately, Miss Wilson did not consider future collectors when she opened her mail.

I picked these three for...
Top - the nice clean Fredericton postmark and the cork cancel.
Middle - the Boisetown postmark (a small farming community even today, I wonder if it's a DPO?) with the inverted map stamp.
Bottom - the Registered letter marks plus...

...the wax seal on the back.

Two impressions. An animal - possibly a dog or a horse - and some initials.
