Here is a picture of the Alfreton label used on 1 April 2004 (was this the first day??)
These are digitally printed like the present P and G labels, but in a layout which copied that used for the Horizon labels introduced in 2002.
The Alfreton label shown was used in connection with Manchester Postal Museum.
We'd be interested in showing any other early labels from the experimental period. What have you got?
