Definition of "connoisseurship"

Reluctantly Bradly unrolled the canvas, which the trooper took from him to hold at arm's length, shutting one eye and crocking his neck sideways in a severe exercise of connoisseurship. Not satisfied with that system of inspecting a view, he had Cooley hold it against a biscuit tin, which required Cooley to cock an eye sideways to inspect it.
