Les curieuses origines des inventions et découvertes / par Ernest Soulange
A French illustrated popular-science book by Ernest Soulange, published in Tours by Mame et Cie in 1848, aimed at general readers curious about the origins of inventions. The two pictures are binding covers rather than text illustrations: gilt and cream ornamental panels with a central oval cartouche, scrolling rococo borders and a lettered spine. A designer could draw on the symmetrical rococo frame and the gold-on-olive tooled pattern for period decorative borders and cartouches.
