The 100th anniversary of Arnold Machin’s birthday will be commemorated by a souvenir sheet available only from Stampex on September 14-17 and from Tallents House.

Litho-printed by Cartor, it simply comprises a block of ten 1st class gold stamps with a modest inscription at the top and a reproduction of Machin’s signature underneath.

The stamps are gummed, with a security overlay but no slits. It’s thought the source code letters in the overlay will be ‘AM’ in a tribute to the sculptor.
