Nicky, You say there is an exact duplicate of this 11x14 on eBay as a print for $10 as an 8x10? I can't find it. Post a link? For $1200 you should have link ink! Have you been able to see the ink? I can not find the link I said I'd post that shows the various inks blazing color in the glare, but it should show easily enough. Look at your other graphs and compare what you see.
