Steve - I believe those are cards that have been trimmed..it's kind of hard to tell though because the edges are smooth either way.
David - I agree with you. I think they probably could have shown scans of more of the cards instead of just the few. Also, some items were not described very well. When I read "underdeveloped" I thought that was referencing cards that had been developed but were really really faded. Instead, I was pleasantly surprised to find that the cards were completely intact with their original backing.
Also, the yellow Tattoo Orbit wrapper, arguably the neatest item in the whole lot was not mentioned at all. It's a very bright, attractive yellow wrapper that mentions the company. Definitely stands out in this lot and is a neat collector piece all by itself.
Not that I'm complaining mind you...I'm very happy with my purchase from Legendary
