Traité des couleurs matérielles et de la maniere de colorer relativement aux différens arts et métiers
A treatise on material colours and how to colour them for various arts and trades, written by Lepileur d'Apligny and published in Paris in 1779 by Saugrain and Lamy with Barrois aîné, aimed at painters and craftsmen. The two pictures are small printed ornaments: a scrolled acanthus cartouche with a shell at its centre, and a symmetrical sprig of leaves and a flower bud above the words 'A PARIS', useful for a designer seeking period tailpieces, dividers or decorative borders.
