Pieter Hendrik Schor (1879-1945)
Cacti. 4 watercolours. Each 31 x 21.5 cm.
Probably made for Pette's Cactus album which appeared in 1931 with illustrations provided by Schor. However, the present four watercolours were not included in the book. An alternative version of one of the plates ("Nacht Cactus") appeared as the front cover for the album. The picture card album is added with this lot.
