I've done tons of online banners during my years as a graphic designer and I think they are too small works to have a post of their own. As clients have requested to see some of them I created this great dump of banners.

Do note that some of these banners are also animated GIFs and only work as you click them open. Some are also social feed banners which mean there are no CTA or long copies as those are added to the post itself.
