(1958, Susan Hayward)

“Hayward rides a prewar GM transit. Interesting thing to note is in this night scene when she gets off the bus and it pulls away, you can see a silhouette of the bus as it goes under an underpass. The driver is the only one on the bus, yet in the interior scene just before Hayward and several others get off the bus, it is nearly full.” (thanks Bruce Korusek) .
It's a 1940 Yellow Coach.
