I have a blog where I post some good promotions I find in my niche. When these promotions expire, I want to have a way to show this in post and on the feature image. Maybe like a banner overlaying the feature image that would say “Offer Expired”.
My idea was to make it somehow with ACF and add a filed which would let me choose if this is expired or not. I would also like to add a note in the first line of each post when it is expired.
I am back to WP after quite some time of pause, so I need help how to achieve that.

Add a class to the image when expired, and add a overlay with some CSS and ::before/::after pseudo elements?
