This series consists of cards of the WYNPHOTOPRINT series which have been hand coloured.  See that series for further details.

The colouring was probably done by the printer, rather than by Selwyn Cox, as they show 'Hand-coloured series' printed in the attribution on the back of the card. 

The numbering and identification in the series is a bit erratic. Most card show the Selwyn Cox diamond-shaped logo of S over C, but it is not always present. Some cards have Selwyn Cox's number beside the logo, but it is not always present.  Some cards have a very small number starting with A, in script, written into the image, but again this is not always present.  It appears that this number was applied by the printer during preparation of the image for printing.
