Star Wars.com has revealed the first 2 of 13 new pieces of art for Star Wars Celebration V from artist Randy Martinez. Here's a quick snippet:
"The Star Wars Roller Coaster was quite a challenge to create. Steve Sansweet [Lucasfilm Director of Fan Relations] gave me the basics of the idea, and one demand. The demand was that the roller coaster car and its passengers be upside down.
"It was more of a challenge than you might think. Since this piece was going to be for advertisement, it had to be both READABLE and eye-catching (design-wise). Putting the characters upside-down creates a problem because we are all used to seeing the characters right-side up. In order to care why they are upside down, we had to do some storytelling in the art, something that people can relate to."
