Roger Water's The Wall Tour Lithographs run confusion

[Davemartin01]

Hi guys & gals,

First post here because I have been pondering something for a long while now... when The Wall tour was first announced a couple of years ago (Iam UK based if that helps) that there was a limited run of 500 The Wall tour Lithographs on the official website. I purchased 2 at about £70 each and are fabulous. They are the large approx 3ft x2 ft.

I then noticed another run appeared of, I think, 2500. Then I saw some appear and no mention of run numbers. Can anyone let me know what the run was of all these lithographs and what the differences were. Was the run of 500 I bought different?
I have never seen anywhere else mention this run of 500 and have never seen them appear on ebay and curious to know what the deal is with it all.

Did the original 500 sell out so they thought of releasing another 2500 thus undermining and devaluing the original 500 run?

I only want to know so I feel like I bought something a bit more special as I want to get it framed finally!

Cheers in advance!
