LTE Central Road Services, Dept of the Operating Manager, Traffic Circulars vol.37 1-26, 6.1 to 21.12.1956, part leather binding rubbed in places with small loss at top of spine

6″ x 4″ oval “BRISTOL TRAMWAYS CAR LICENSE” has the appearance of slate but I think it is zinc, the centre part has the number 153 formed inside an area filled with a red substance which could be crazed paint or wax, 2 screw holes, the misspelling (according to English usage) of “LICENSE” is because this is the plate from a car made in the USA so American spelling has prevailed
