BBC Radio 1 "1" radio - 1988/89
Radio 1 branded battery-operated radio in the shape of the number 1 and featuring the 1988/89 station logo.
These are a tie-in with Midland Bank, whose teenager account was called the Number One account and these radios were presumably given away to those opening a new account.
The old Midland Bank logo features on the side of the box for extra retroness.
