The Mailbox is this week’s Friday Photo. It used to be the old Royal Mail sorting office. Below is an old image from the Mailbox website which has a brief history of the development.
Other Images – Birmingham Mail archives have a great old image of the sorting office taken in 1979 when its operation ground to a halt over a suspected terrorist device.
Birmingham Postal Museum & Archive has some interesting information on postal history in England, like this photography of a travelling post office between London and Birmingham.
