This is small series of coloured cards printed by photolithograohy by Stengel & Co of Dresden, Germany in 1910.
These cards have the usual Selwyn Cox diamond logo on the front, but some of them show "Len Wilkinson, Post Card Depot Launceston" on the back. I am regarding these cards as published by Selwyn Cox for Len Wilkinson.
Date Published: Usage dates on two of the cards are 1910.
Printing: Printing was by colour lithography over a black collotype base layer.
Number in Series: Unknown. I have seen less than a dozen cards.
Identification: These are identified as the Wynchrome Series by the imprint on the back of the cards.
Numbering: As well as the Selwyn Cox number beside the logo, some cards have a very small number starting with A, in script, written into the image. It appears that this number was applied by the printer during preparation of the image for printing.
