2002 Lighthouses of Australia - Mini Sheet format - unique Se-tenant Block 4 configuration

The 2002 Lighthouses set was also issued in a unique 'Miniature Sheet' format in a limited edition booklet and, as such, has neat staple indents at left side. The set is configured in a joined 'Se-tenant Block 4', not as a se-tenant pair and two singles, as per the regular-issue stamp set, so it is unique in this regard.
