QED Publications, 1998
Edward Wakeling is a former chairman of the Lewis Carroll Society. His interest in Lewis Carroll apparently began in 1975 when he attended an exhibition at Hatfield House, Hertfordshire organized by the Lewis Carroll Society. This started an interest in collecting Lewis Carroll’s works, and he now owns one of the finest collections of Carroll material in private hands. (I’m planning on rivalling him eventually ;) )
1998 marked both the centenary of Dodgson’s death and of Escher’s birth this calendar explores the life and works of them both, with important dates highlighted, and lots of puzzles and games.
There’s a page exploring Dodgson’s interest in the number 42 (said to be the reason that Douglas Adams chose it as the ‘answer’ in the Hitchhiker series).
There are also pages on Alice in Flatland, Escher and Möbius Bands, Morphing and Golden Rectangles.
Out of print, but occasionally available on Amazon: Alice in Escherland
