The first version I'm aware of was the Kos version. It has the speck/spot/flaw below the E in Certification. It also has OHBM in the lower left corner.
The next version I saw was from 0bama's website. It appears to be identical to the Kos version, except for size.
Then along comes FactCheck, with their version. It has the speck/spot/flaw but has OHSM in the lower left corner.
Could it be that the original (nearsighted) forger mistook an S for a B, and that error was 'corrected' by the good folks at FactCheck ?
