Jane Audas from www.shelfappeal.com just sent me a link to this wonderful book cover.
"Her splendid and richly illustrated survey of English vernacular art - with material on taxidermy, fairgrounds, canal boats, seaside, riverside, tattooing, the decoration of food, waxworks, toys, rustic work, shops, festivals and funerals. Based on her influential series of articles for the Architectural Review - The idea of ‘popular art’ as a subject for academic study can, I believe, be almost entirely sttributed to the writings of Barbara Jones and Erica [i.e. Enid] Marx, and this book in particular broke entirely fresh ground.”
