the Green Man festival in Clun (Shropshire) is recent

One thing I'm trying to establish is at which point the Raglanite Orthodoxy of 1939 entered the popular consciousness. Kathleen Basford's seminal - however so circumspect with regards to Lady Raglan's conclusions - work on the subject is 1978, though Anne Ross had all the Raglanite bases covered by 1975 in her Grotesques and Gargoyles. The pub in The Wicker Man is, as we've seen, The Green Man, indicating a certain awareness, though in popular books on Mythology, Folklore and Witchcraft from that time (your local Wetherspoons is a good place to look!) the Green Man is conspicuous by his absence.

In more specialist scholarly works, such as the King Penguin volumes Medieval Carvings of Exeter Cathedral (Cave, 1953) and Misericords (Anderson, 1954), we find the Raglanite Orthodoxy firmly in place, though oddly enough both volumes avoid the term Green Man when naming the plates, preferring Foliate Mask and Head-with-Leaves respectively.   

Am I naive to imagine the average Mudcatter's bookshelves to be bending down with all manner of folkloric reading matter? If not, then please be so good as to cast an eye over your precious tomes and see what you come up with...
