GREAT BRITAIN 1969 (USED) 1S6D LIVERPOOL METROPOLITAN PRE-RELEASE PAIR
1s6d Liverpool Metropolitan Cathedral pair on-piece with parcel cancel dated 5 FEB 69, over 16 weeks prior to official release. However, rather than the stamps being pre-released, it's believed the parcel hand stamp was incorrectly set. Unusual. Generally fine. SG801; SC594
