Actually, there seems to be a very very small shift of the picture in Cartoon B when compared to Cartoon A; when compared, it appears that part of Cartoon A is cut off on the right compared to Cartoon B. Also, Cartoon A has more on the left than Cartoon B. It's not likely that this difference is significant enough to be the tenth difference you are looking for, though. Also, there is a dot in front of the racecar in Cartoon A but not Cartoon B (next to the person's leg whose pocket is missing), but this isn't likely to be anything either.
For the record, I sincerely doubt that there is a tenth difference. If there is one, it's one of the two that I mentioned just now, and probably the dot. If it is, I demand rep from every last one of you that actually tried to look for a difference. know for a fact there isn't a tenth record. I just went into Paint, copied one picture and then pasted it onto the other, and then sat there undoing and redoing it. Nothing else fucking changes, with the exception of a few dots and the thickness of a few lines. Also, I would like to amend my previous statement that there is a shift in the picture from Cartoon A to Cartoon B; it actually seems to be a slight counter-clockwise rotation.
