Having reported here on some very early MACH1 pages (from prog 4) sell for £1,287 and here about a single page from prog 3 go for £1,200 I see that the same seller has 2 more pages of original art up for sale...
These are from prog 16 (pages 26+27) - the art is by Pedro Martinez Henares (his only 2000AD art apparently).
At the time of typing the price has been bid up to £310 - I'd expect it to go much higher. Good luck if you bid.
The pages are here - boom! sold for £770
