Nothing is obviously scarce about this 4.4-inch ambulance made by Barr except its condition, which is exceptional especially given that rubber toys were quite susceptible to warping. Nothing, that is, until one looks at the roof. Thereon imprinted in red is the distinctive logo for Poll Parrot Shoes. That logo, which matches the red crosses on the side panels, is pristine because in the succeeding decades no one has tried to clean or wax this toy.
