Papillons by E.A. Séguy (Emile-Allain), 1877-1951, was published in Paris in 1925. The work features 81 sublime images of butterflies (papillons) in 16 tableaux.

Writing in the introduction, Séguy explains that the rarity of some butterflies, their fragility and the high price out on them has led to a dearth of illustrations, which he sought to redress in a single volume.

He obtained the specimens with "great difficulty". And after working with gouache and watercolours, produced "reproductions free from any interpretation, as well as from any fantasy".
