Well, even after 5 months preparing for this intense venture/video, this youtuber is still puzzled by the Dick Green card's image...one of the few action shots he could not narrow down and identify a date for based on the image used in the 1973 set. Did the youtuber mistakenly think an error was made?
Overall, an awesome video and well worth watching the entire video. The link will take you to the chapter where the Green card is discussed.
