The cards are a yellow color pass, and one with just yellow and blue color passes. The front printing plates are an image only, text box added, number added, and caption added versions. The backs of the cards may not have been terribly colorful, but multiple print passes were still needed to create the 3D image. Here we have two plates for the back image - 1 dark and 1 light. The cards are hand cut from a sheet and may not receive number grades if submitted. We do have other color progression cards from this set in the auction that did receive number grades. To the best of our knowledge no one grades the printing plates. Oddball
