Montreal Urban Community Transit Commission 1980s Roll Sign
Montréal's buses had a split front destination sign, with the route number and name displayed on the left (facing the bus), and an auxiliary sign on the right; however, the auxiliary sign was usually set either to blank or "MÉTRO".
Judging by the routes listed (and the GARAGE destinations at the end), this sign came from a bus assigned to one of the west-end garages.
