Context

“but it is a most clingingly exact translation of Dort Oben Wunderbar—fits it like a blister. Mr. Garnham’s reproduction has other merits—a hundred of them—but it is not necessary to point them out. They will be detected. No one with a specialty can hope to have a monopoly of it. Even Garnham has a rival. Mr. X had a small pamphlet with him which he had bought while on a visit to Munich. It was entitled A Catalogue of Pictures in the Old Pinacotek, and was written in a peculiar kind of English.” source
