This card with a divided back was used in what appears to be 1905 but I thought the divided back wasn't adopted or allowed by the post office until 1907. Is there an explanation for this or is my understanding incorrect. Cheers, Bill
The divided back postcard was introduced in the UK around 1902. This is, I think, an English-made, Welsh-themed card distributed by a Canadian company, hence the UK back design. Just my theory, of course!
