Unfortunately the way I can usually tell the difference on the A is with the slight color differences. Based on those yours are also indeed in the minty white bootleg group. That being said though, cameras and lighting can affect this so without much better shots or having them in hand I cannot put a 100% yay/nay stamp on them.
Matt, I need to find the drive with notes and pics I made from looking at the 1S style A bootleg. The short answer for identifying them is to look at the light saber trail on the left side. In the normal one sheet the color looks to be blue/white gradients. In the bootleg there is a definite tan tinge to the trail especially next to the saber. The paper was off as well, the back was rougher than normal 1S stock from the time period and slightly thinner, closer to Australian 1S paper from the period.
For reference to date I have physically held "bootlegs that don't exist" for Star Wars 1 sheets including SW second advance (silver one), Style D, EMP A, Jedi A. Any others are already well known. All but the second advance seem to be made by the same printer/person as the paper stock is the same.
