By coincidence, I was only today looking at the art of Tibool, DeLucena and Nikolai Bessonov -- I am reasonably certain that the first two are pseudonyms for the latter. There is a nice discussion over in the prison girls thread (
link) and there is a more extensive free Tibool gallery at Mark Desadov's site (
link to the first gallery page, then follow the link at the bottom for a further 10 pages of images, several hundred in total). I think I prefer the DeLucena and Bessonov incarnations over the Tibool images, but they are all very fine.
