I only have a few backgrounds in my archives from all the Lucky Charms commercials I worked on in the 1990's. Here are a few. As you can see, this style and color palette is very different from the revised and updated palette in the two previous posts.
This background is a four foot long painting used in a pan camera move from left to right. Lucky was flying through the air in this particular scene. I think it took me a week to paint it. Too bad I can't show you a larger version. I think I had scanned it in sections and put it together in Photoshop.
