More news on security (slit) stamps.
I recently had reason to contact Douglas Myall. In his reply to me (on a separate subject) he states that.
"Of the security stamps announced for 17 February, the coils have been cancelled and the Walsall products have been postponed for six weeks to 31 March."
I am assuming this cancellation and postponement are due to technical problems at the printers.
Douglas continues: "Images with the iridescent overprint going over the Queen's face are incorrect. I don't think HM would be too pleased if her image were to be sullied in this way! Like the Iriodin ink which it replaces it is confined to the background."
Thanks Douglas, all new information is gratefully received.
