Special thanks go out to billyjane for introducing me to this wonderful artist!
Boever (1872 – 1949) was a Flemish Symbolist who produced some lovely illustrations to Baudelaire’s Les Fleurs du Mal. He specialised in erotic portraits of women, almost always in macabre or bizarre settings. He was very successful until around 1935, when he went dramatically out of fashion, and was never able to achieve his former popularity. I’ve found a good website on him here offering a more extensive bibliography and gallery.
