I have a whole book of them at home, published around the early 1970s I think. I found it in a second hand shop at the little town of Gulgong in New South Wales, Australia around 10 years ago.. complete with cartoons by Bill Tidy.. cost me $2 (Aus)... absolutely brilliant. Not much help to you, I guess, but there are a couple of Thackray sites I have come across on the net.. maybe the spelling you used stuffed you up. It is Jake Thackray.. good luck.
