As someone who has a significant investment (emotional and financial) in maintaining the integrity of authentic signed T206 cards, I wanted to collect all of the information about the recently identified signed Marquard forgery in one place, in a helpful chronology. I want it all to be at the top of the posting so that updates on the status of identifying the forger, if any, can be included in one post and at the top of a thread.
If you have additional information, please send it to me, or post it below, and I will add it to the chronology.

Again, if you have additional information, please send it to me, or post it below, and I will add it to the chronology. There are too many witnesses to these events for additional information not to become available over time. As it does, I will compile it here.
