I was curios about the circles to the left of the date and the number eight that can be seen below the date. There are also circles the are grouped together and a number five that is visible in the upper right hand portion of the Lincoln memorial. I just uploaded other images where a number eight can be seen in the lower left hand portion of Lincoln's upper arm. and a circle on Lincoln's upper jaw below the ear. It almost looks like Lincoln is wearing an earring. Again, thanks for any comments and feedback.
