Do you have a less blurry image?

Trophy Icons are 16x16 pixel, so you will see the original image if you zoom out all the way on the imgur image. That being said, it is not clear at all what image this is, and the general community can't help with this. Where have you seen this trophy? In the main page of the site, or in a specific game page? If it's the latter, you can go through your browser history and see which games have you looked at.

How do you have a screenshot of it?

Perhaps check your browser history and see which games you've looked at?
