Hi Fergol - Try and get hold of 'The Almost Impossible Crossword Book' by Gyles Brandreth. I bought the paperback in 1984 for �2.50, published by Sphere Books, ISBN 0-7221-1864-3. There are 52 puzzles, including the World's First Crossword Puzzle and the 'Smallest Ever' (just ONE square!). Absolutely wicked! Incidentally, 'The Largest Ever' (which is mentioned but not included) covered an area of 18� suare feet, with 6,257 across clues and 6,051 down clues. Solve that!! Regardz, ja
