The painting of the Y-wing assault on the original Death Star was also one of the earliest, completed in February of 1975. It featured Ralph’s original design for the Death Star’s weapon. “My concept for the Death Star laser cannon was one that would charge up deep within the core, focus its energy and fire through the opening in the surface,” he said.
Unlike so many of his others, this particular painting was not signed by Ralph when completed, which has led to some confusion through the years as to the proper orientation of the image. Ralph confirmed that the inverted Y-Wing, as it appeared in the original Star Wars portfolio, is in fact the way he conceived it. It currently is inverted in the Lucasfilm digital archives, so you will occasionally see it reproduced with the Y-Wing’s right side up (not that it isn’t an effective image either way). Most recently, it appeared (in the proper orientation) in Ryder Windham’s Death Star Owner’s Technical Manual.
