Can you find an example of a hyperbole in a newspaper advertisement?

Many places you can find is in adverts. Like 'best windows you can find' or 'Sale of a lifetime' these are all over-exaggerating, and this is what a hyperbole is.

I find that the word 'Only' is used to the extreme in adverts.

'Only' implies something small.

'Only' one page left to read, 'only' 2 seats left, and so on.

To see an advert advertising a really expensive item with the word 'only' always seems like an exaggeration.

It tries to make people think that the price is good value, but it might not be so.

Yes, here is an example of a hyperbole in a newspaper advertisement:

"Get the best burger in the universe at Joe's Burger Joint!"

In this advertisement, the phrase "best burger in the universe" is a hyperbole because it exaggerates the quality of the burger to an extreme degree. It's highly unlikely that Joe's Burger Joint actually serves the best burger in the entire universe, making it a clear example of hyperbolic language used for emphasis and persuasion in advertising.
