It seems likely that he sent some specimen cards to the Postmaster General to see if they would be approved.
In January 1902 the Editor of Picture Postcard Magazine published a statement, at the request of the Postmaster General, which said that "... the address side, a continuation of the message, or the name and address of the sender, or even an advertisement, so long as such matter does not interfere in any way with the legibility of the address.
This was posted in 1906 but may well have been printed any time after January 1902. is an early divided back card, which contains another clue about age - and the C W Faulkner only became a limited company in 1905.
The publisher of this card is not known, but the instructions have all been put on the address side - maximising the areas for the message. The picture and coat of arms were used in an earlier undivided back card (q.v.).
As there was now space for the message on the address side there was no longer need to leave space for a message on the picture side, and pictures expanded to fill the whole card. Information relating to the differences between inland and foreign use were included in the stamp box, which is obscured when the card has been posted - although the postmark may well give the date of posting.
Stamp boxes are the small rectangular boxes printed on the back of some postcards, where the stamp is to be stuck.
