He, he Clint, maybe you are right....
We don't even see the flip side on the photos from the 9th. They seem to be uploaded differently as well. But no seller's name (as far as I can tell) and when comparing the "other text" on each e-bay page, they seem very, very similar, so I really don't know.
Two different seller's, on such an extremely common topic (can't get my tounge further inside my cheek) as old Austro-Hungarian aircraft? Hmmm, does the lightning strike twice at the same time? On e-bay??
Last time such a miracle happened was perhaps 2000 years ago....you know, the guy who walked on water....
Joking aside, no I don't know. If it is then it is indeed quite incredible....
Cheers
