Stair Dog by Jacques Dropy

No information online. Here is what my little paperback copy of "The Best Cartoons from France" has to say:
"Dropy learned to draw before he learned to write, a habit which caused him to fail consistently in school. His first group of cartoons were unanimously rejected by the editors who saw them. Perseverance, however, won out, and his fantastic drawings are now happily accepted everywhere. A man of violent feelings yet sentimental thoughts, he keeps two portfolios—one titled Monsters, which is self-explanatory, the other titled Bonshommes, in which his milder ideas are collected."
