The photo at top of that page (and on the mimeo link for a better photo) is John Bennett Mimeo printing an issue of Vagabond, which most likely had something by Buk in it. Very cool to see someone printing small press back in the day. It is surprisingly rare to see things like this.
I love seeing these kind of photos. Reminds me of Brother Antoninus in front of his hand press, d.a. levy setting type and Anais Nin running her 8"x12" Chandler & Price. I think that I have seen one of Virginia Woolf at the press too?
There is a similar lack of photographs of the brilliant american woman Sylvia Beach, publisher and book store owner of Shakespeare and Company in Paris ( along with her partner Adrienne Monnier) at it's peak in the inter-war years. First to publish James Joyce's Ulysses in book form ( interestingly - rejected by Leonard and Virginia Woolf at Hogarth House). They saw all the major writers of those years through their doors. There is this of them with James Joyce:
ps: there is this illustration of Virginia Woolf at her press by Richard Kennedy who worked there as a young lad (skivvy) and later published an illustrated book about his time there with them: A Boy at Hogarth Press - not quite the same though.
