hi all, maybe of interest, in the early 1990s i worked at UNSW and met several people in the computer science dept who knew John Lions. i *was* the character on the cover of the reprint, i have a photocopy of the original pamphlet, complete with hand written annotations by someone who attended Lyons course. perhaps everyone on tuhs has their own photocopy, but if anyone wants this one, give me a shout. -Steve
