In which year

[Mickeymouse]

did the Royal Mail sanction the sending of postcards?

[Joshua_R]

Postcard was patented in 1861 in United States, but didn't get adopted by the Post Office in Britain until 1870. Original cost was the price of the stamp printed on it - a halfpenny.

First picture postcard in Britain was 1894.
