One of the cards that has continued to elude me for my Chris Brown collection is the following:

2007 Artifacts Parallel Autograph

My question is this.......what exactly is the difference in the parallel as opposed to the regular? I have found a few differences with these cards, for instance, I have a version that is in blue ink on a clear sticker, one with blue ink on a silver foil sticker and one with black ink on a silver foil sticker. I have no idea if any of those are considered to be parallel.

If anyone has the info, that would be great! Thanks for your time.
