L'héliochromie : découvertes, constatations et améliorations importantes : lettre à Monsieur le Président de la Société française de photographie
A French pamphlet by Louis Ducos du Hauron, printed in Agen in 1874, written as a letter to the president of the Société française de photographie about colour photography. The only picture is the title page, which shows a large capitalised heading with a small ornamental rule and an oval library stamp from the École d'art de Bourges, so a designer would take from it the classic 19th-century French title-page typography with centred capitals and a flourish divider.
