This printing firm was started by Aneurin Williams (1859-1924) Liberal politician and friends. They were deeply involved in worker partnerships, co-ops, garden cities etc. and aimed to see if a group of skilled workers could control and staff a company like this, with capital supplied by others. I gather it ran like this as a worker partnership until 1917, when most of the staff had been called up.
It was in the main a commercial printer of books, journals and had a bindery, it moved to Letchworth in 1905 – the first printers in the first garden city – and by 1907 there were a whole cluster of printing operations there, including Douglas Cockerell’s bindery.
They also produced limited editions of literature, some for other publishers and some like this one published by themselves.

Private Press & Wood Engraved Books 
Very interesting entry. I have come across a number of books printed by this press and would like to know more. Where did you get your information about the press here, and is there somewhere I can read more about how it functioned in it’s early years? Thanks.
G S Tomkinson bibliography of modern presses p. 198 has a few words. Will Ransom private presses and their books has a sentence on p. 289. Otherwise I think I just got bits from Google searches, but could not find out anything in detail unfortunately.
http://www.gardencitycollection.com/home – searching for Garden city press at this site brings up some press clippings etc about the press, some 1906.
Thanks very much for those sources. I will take a look. I find the idea of a cooperative printing press fascinating – especially within the context of Letchworth. One of the town planners of Letchworth was Raymond Unwin, who was associated with William Morris via the Hammersmith Socialist League; so, an interesting connection between Kelmscott and Garden City there.
