More about the Gerry Anderson Thunderbirds issue, especially the lenticular MS on the Creative Review Blog.

"Perforation of the acrylic stamps then took place at Cartor in Paris alongside numerous UK cancellation tests in order to perfect the quick-drying franking machine ink chemistry required."
Does this mean that Royal Mail will change the canceling ink at all of its processing centers just for this stamp issue?
....which must have upset somone at RM (again) because it's gone.
