Different shades of yellow were used on the later printings of Road, varying from pale (which is rather attractive) to quite bright. I happened to have a late 1940’s/early 1950’s copy with the bright yellow background that I dislike. I masked the cover using frisket (an adhesive film), and cut out the background areas. With a couple passes of gold spray paint, I had created a non-existent variant of the book! The above photo shows the result. The book on the left is another copy
of the standard cover, and on the right is my metallic version. It didn't take long, and the result is actually rather attractive!
