I know! I don't have access to printers like that anymore, so I can't make one. Most print shops will not due to copyright issues. I have several Duke Nukem posters, but I know what you mean.
I did get one of the Standees from DNF at least and then ChrisF over at GearBox was nice enough to send me a high-res face image of "the twins" so I could make this, and use it as a giant poster basically.

I know you are probably typing more about Duke from 3D... and I would love to have one of those.

It is just like with the Star Wars movies. I saw episodes 4,5,6 in the theater as a child, and their impact was great and I have great attachment to them. Episodes 1,2,3 I have watched several times each and I just can't get into them at all. It is the same with Duke Nukem 3D vs Duke Nukem Forever, but not as extreme.
