Spoddendale route map late 1970s

A map showing the Spoddendale network in the late 1970s which appeared in the timetable leaflets created at the time. A3 photocopiers were relatively unknown back then so my work was on two A4 sheets that had to be taped together. Forty odd years later the effectiveness of the tape had deteriorated and the two sheets are again separate! Plus it had left a brown mark where it had once been.
