So, so many to choose from , so for a personal faves roll of honour: MSH, He Knows you Know, Assassing, Kayleigh, Sugar Mice (would have been better as the album cover for me, particularly as CaS was not a gatefold), State of Mind, Suits, Goldfish and Clowns, Dark Angel (on 13th Star), Perfume River, Masquerade in Silence, Thistle Alley, The Leaving, Great Unravelling (yes, I am very
happy with my 'Feast' book
But, if I have to choose absolute favourites, then I would say 'Misplaced' for a striking album cover, while Dark Star is the painting I would go for as pride of place on the wall (well, everything to the right of the naked man !).
In all honesty there are very few I don't really rate- Thieving Magpie cover easily stealing that title.
