Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

If there is another bike in front of the main bike with the fender, how come we don't see the fender of the front wheel of the other bike? I have put an exclamation point over the fender that we see. Well, they are claiming that that is Hargis' fender, which means that Martin's fender must be in front of it, that is, to the left of it and within the viewing field of the camera. So, why don't we see Martin's fender below where I have the question mark? 

Remember that the bikes are on the same road, and the height and size of the bikes are exactly the same. The height of Martin's wheel is the same height as Hargis' wheel. Hargis' supposed wheel is way above the bottom of the picture; we are seeing it boldly. So, shouldn't we be seeing at least some of Martin's fender? How could it be completely missing from the picture?
