That book you were talking about was the 1985 Bus Guide. It came
together with a Bus Map. The book had a shadow of a B57 on its
cover with a map of the CBD in the background. The 1984 Bus Guide
was pocket-sized, made from inferior quality paper and cost 70c. It
had a grey cover with 4 coloured arrows intersecting each other. Go
to the TIBS Shop at Yishun Interchange if you would like to see how
they look like.
