For me what always gives it away is not the posters themselves, it’s the context. These are all overdesigned for a local community fair. There is no way they’d be paying for a professional designer for this, therefore it’s AI.
On the other hand if it had word art, grammar/spelling mistakes, images with wrong aspect ratios or clipping issues, that would immediately convince me it wasn’t AI.
