This image is reblogged from a 14 January 2014 post at Infernal Wonders. Although none of the sources have an attribution, by style I’m pretty sure that it is the work of Canadian artist Barry Blair (1954-2010). The image appears to have first been published on the tumblr Effeuillages coquins (sadly now defunct, but there is an imperfect Internet Archive copy here) and comes to me via another tumblr Fifi — Feeling is First (also sadly now defunct, but there is an imperfect Internet Archive copy here).
