Update on Machin Souvenir Sheet due 14 September

We have been given new technical information on this sheet.

The sheet is printed by Walsall using the Gravure Process & has PVA Gum


No word yet on whether the design has been improved from this preliminary, or on what the security codes will be, although 'AM' has been suggested - ROYAL MAML ?

Postmarks for the date of issue are here
