Quotations
The unhappy man (who had cheated the sailors), innocent of danger, is seated on a grating with his combs, spy-glasses, necklaces, ribbons, and all the rest of his "Brummagem" trumpery, spread out before him.
1893, Graham Everitt, English Caricaturists and Graphic Humourists of the Nineteenth Century, page 175
"My, my, my, my, my," said a voice from behind them, and the Baudelaire orphans turned to find Stephano standing there,...a look of brummagem surprise on his face. "Brummagem" is such a rare word for "fake" that even Klaus didn't know what it meant, but the children did not have to be told that Stephano was pretending to be surprised.
