Lindsey Buckingham's <i>Law and Order</i> on vinyl

[kroessman]

I'm trying to figure out if I have something really collectible on my hands. I have a copy of Lindsey's Law and Order on vinyl, and it's a promotional copy stamped by the label. The sleeve and record are in great condition, but I have no clue whether this record is more or less valuable due to its status as a promotional issue. I'd be glad to post some pictures if anyone here has knowledge into that kind of thing
