I don’t remember who created it but this is a Dungeon World event banner for Google+ events. The top part is what shows under the preview for the event and it centers perfectly on the DW part of the banner. Bottom part of the image is how the banner shows up viewing the full event.

Maybe Daniele Di Rubbo ?
Yes, I did it. 😉
