Unfortunately, I don't still have a copy of this book, but I found an image of the cover on the web. I do remember working on it, and some of the interesting problems it posed: How do you draw a pool of light in pen and ink? How can you make a tupperware box containing a half chewed Mars bar look eerie? What does a footprint actually look like? (And yes, I whipped off the shoes, stood in a puddle of paint and stamped on a sheet of paper to find out - this was before you could just google these things).
