Fair enough, perhaps not "cosplay" as a broad definition, but in the sense of modern fandom organizing "cons", I found it interesting it went back decades earlier than I'd assumed. I knew there were Star Trek conventions in the 1960's, but I would've never guessed as early as before the US entering WWII. Of course costumes and enjoying stories probably date back to before writing, but I thought the modern form was much newer.
