LIST OF POSTCARD PUBLISHERS

 

 

Mentioned on my Postcards page, 'Picture Postcards and their Publishers' by Anthony Byatt, ISBN 0 9506212 0 X is a useful book.
This American web site is also worth a visit: http://www.metropostcard.com/metropcpublishers.html (use A-Z at top of page).

I have put the following list of publishers together, by their initials, from various sources.  This list is ongoing and I add to it whenever I find a new publisher, or whenever anybody sends me corrections or additions.  Dave Tylcoat, Devon, England.

SAN BRIDE ; I have included this here because I often come across postcards with a Trade Mark of a church steeple (it is St Bride's, Fleet Street, London) with "SAN BRIDE" under it.  I was assuming a London publisher was using this as their Trade Mark (St Bride Printing, Bride Lane, Fleet Street) - but in 1925 there was a 'Sanbride Press' in Middlesbrough (Hood & Co, Printers) - using the steeple as a Trade Mark - they did print postcards.  It has been suggested that the Middlesbrough printers trained in London & took the name with them.
