Or some other version, it doesn't matter. I see a lot of those pictures with '例大祭 おつかれさまでした!', or for other conventions, and many of them are filed under translation request. This is not a line that's really worth translating for the most part (I suppose I'd say something like 'Good job at Reitaisai, everyone', or something like that), but it's not worth removing from translation_request either. So, bunch them all under a tag.
Opinions/flames/whatever are welcome.
