We are a family of Postal employees...and appreciate anything postal related. Especially post boxes. :)
I've received many from Japan, and I love this collection: "Mailbox card".
They are called "ポスト型はがき" in Japanese...
We retired from the post office and work at my photography full time. I live with my wonderful husband in a quiet town a few hours from the Capital Ottawa. I am forever grateful for my 3 grown children and 5 lovely grandchildren.
PS... if you would like to see some of my photography...
