The version posted on 0bama's website has OHBM in the lower left corner. The folded copy with serial number which has appeared in photographs has OHSM in the lower left corner.
A case of too many forgers spoiling the broth ?

If you look, all versions but the one posted on FTS has OHSM in the lower left corner, not just the photographed one. I’m curious as to why Polarik didn’t mention this and explain why there appears to be two versions. Perhaps it was a typo that was fixed but they forgot to send the corrected version to FTS?
