Well, I'm not too surprised and I had already strong doubts about it being a lunar. I guess that I got what I payed for. :-) /G?ran Norbert Classen wrote: >Hi Don, Martin, and All, > >I've seen close-up pictures of fragments of the alledged "Dho 025" sold on >eBay by "floridacoaster", and they actually don't look like the real McCoy >but more like a vesicular terrestrial basalt.
