Once you have a product page on the Appstore that users can access, Apple gives you the opportunity to add a banner on top of this page. In addition to the screenshots or the video, this is a spot where you can re-enforce your corporate identity and make the page more unique. Here below you will find different batches of banners created for that purposes organised by years (not all of them were published and publicly visible in the store).
