The Vulcan Series postcards appear in many areas of England, often with a local publisher name. They were presumably printed by a company which had salesmen travelling the country. It appears to have operated between the wars and the earliest cards I have located was used in 1921, and the majority which were posted were posted in the 1920s. Most are uncoloured, and none show features that suggest the picture was taken after the Second World War. It may be significant that nearly all the Hertfordshire examples I have located give Post Office addresses.

Guideline: It seems likely very that the pictures on the Vulcan cards were taken shortly after the end of the First World War, and possibly before 1930.

Can anyone tell me anything for certain about the publisher of the series. If you google there are a couple of brief references which suggest the Vulcan series might have been produced by Radermacher, Aldous and Co who printed many post cards for other firms, including the R.A. Series, but I would like to see some firmer evidence.
