In page Asa Benveniste:

"

The artist Pip (Penelope) Benveniste, Asa's first wife, was also his partner in the Trigram Press project and provided the funds for its establishment. Pip's middle son (and Asa's stepson) Paul Vaughan was the highly skilled printer at Trigram Press, operating the classic Gutenberg Printing Press to a very high standard and developing groundbreaking results with silkscreen images for books, limited edition prints and other outlets. Pip died on August 30, 2010 (see Guardian obituary, September 16, 2010); she is now recognised as an important post-war British modernist painter. One aspect of her work - designs for hand-woven rugs - was launched by her youngest son, Mark Vaughan, with her blessing, in 2012 (see www.landrugs.com).[6]
