Many had said it was Paul Shipper behind the Star Wars Celebration Character Banner, I was skeptical as it didn’t match his style, so I did a bit of digging and found it was done by Cristiano Siqueira, a renowned vector illustrator from São Paulo, Brasil.
Here’s what he had to say about it on Facebook page.
“Very proud to finally be able to share this work with you!
I spent a good part of the last year second semester working on these Star Wars characters for Lucas Film. This work will be the key art of the “Star Wars Celebration 2019”, a big Star Wars fan event that happens in Chicago, at April this year.”
Here’s selection of close ups of the key art he shared on Facebook.
