For a few, brief seconds I thought 'longmonth.jpg' might have been spacejack's when it first posted, but only because it had quality and effort, was in black-and-white, and nothing which 'looked' like spacejack's work had been posted up to that point. It didn't take long to realize / think it wasn't him, though; the style isn't his, the "voice" isn't his etc. Then I saw 'deja joue.jpg' and thought it was his straight away: The style fit. Maybe it was just a bald, lucky guess; maybe your perception's not so hot: Who knows?
