[Photolithographs in L'art flamand]

".10 Photolithographs, Procédés Asser et Toovey, from paintings (or monochromatic studies) in tone, some with tint plates, most Chine Collee. With poems on paintings by: Gallait, Leys, Wiertz, . Pauwels, Madou, Stevens, Dillens, Verboeckhoven, Roffiaen. A good example of Asser's process and one of only about five books published using it. This group of plates shows the extensive hand etching that needed to be done on the stone to give any sense of tonal variation to the plate."--Hanson Collection catalog, p. 33
