I'm also extremely chuffed to find myself mentioned in the acknowledgements there. When she was researching the changing iconography of Green Men in pub signs, Jacqueline had asked around for any images people might have. She was thus able to describe a number of signs, including 'The Green Man on the corner of Plashet Grove and Katherine Road (London E6) [that] shows a "wild man" figure carrying a tankard and standing next to a barrel' (p. 121).
Here's the photo on which she based that description. I'd taken it in part because the pub was closing down, and I felt there should be some record of the motif in use there before evidence of it disappeared. The building was subsequently demolished, and a block of flats is nearing completion on the site.
There had been quite a lot of local interest in the pub because it was one of the older buildings in the area. (Although it wasn't a great pub by the time I knew it). I'm pleased that such interest can also be used to inform other research.
