This is a bit of a complicated set for identification purposes. Each card was released with five different background patterns. Additionally, for each of the five versions there was one background pattern for card numbers 1-66 and a different background pattern for card numbers 67-112. So there are actually a total of ten different background patterns!

I won't attempt to provide text descriptions for each background pattern. Examples of each one are available at the following links:
