Postcard Numbering

"The number 3291 indicates the card was published in 1923 (the number is the year, with the digits reversed).

I have (or have seen) other Pelham postcards with the numbers 6291, 7291 and 0391 -  published in 1926, 1927 and 1930 respectively.  

A cunning numbering system, heh?"

"In some cases, the same view was printed over several years (with the number changing).  I have seen the same view on Pelham cards with 6291 and 0391 (2 different printings of the same card).

This numbering scheme seems to have been applied in the 1920s and 1930s.  The cards published in the Pelham series by Boots Cash Chemists around 1905 for instance have a different numbering system, including letters as well as numbers (e.g. 116A)."
