Hi Paul
No, I've never seen a picture cover for it either and sadly don't have £500 to buy this particular rarity. Strangely enough an acquaintance in Nottingham recently told me that he'd just sold a copy which had been found with a bunch of other vinyl on a tip. As my acquaintance and the seller are both in Nottingham and the timing seems right, I suspect these are one and the same copy. It's a small (and expensive) world we live in!
Its funny whats valuable - the illustration is by Sir John Tenniel (from the original 1871 Lewis Carroll novel Through the Looking-Glass, and What Alice Found There, a sequel to Alice's Adventures in Wonderland). It appears poorly reproduced on flimsy paper - like many of these picture sleeves. This would have maddened Tenniel as he rejected the first run of the book due to poor quality paper (it was re-sold in the US). Great song, often comped, anyone know its history?
All very interesting. The back covers of the Rubble LPs made good use of Tenniel's drawings as well I think. Maybe Parlaphone / EMI had a marketing wheeze to put the promos of all their emergent undergorund 45s out in pic sleeves in 1967. Pink Floyd 'the coming sound of '67' and all that? Interesting to see old Hank Wangford on the back cover, I've never seen a psych period photo of him! I never thought to look on cat45, which would have been an obvious thing to do of course! I'd like to find a skip with this kind of treasure in it!
