I like this one for the same reason as Denny, but with HOF I think the challenge is to try to do something with the viking helmets, skulls etc. and put your unique stamp on it. The best HOF posters (IMO) are still the ones with those elements. Certain artists rose to that challenge remarkably well (see Vance Kelly, Jay Vollmar, Bobby Dixon & a few others).
Films were mega-expensive because it was really important to not have the kind of warping you get with vellum or taped together films.
So I went for five incredibly large pro digital films at $125 a piece plus tax.
Worth it - no fuckin about - and these reg'd like a dream. Dot on big muthafuckking dot.
Big and metallic - It's 23" x 35" - and I did the four color process in straight flourescents with a thinned gun-metal metallic for black.
I planned out the four color process for weeks before printing. And printed them out of order and in different ink intensities than if I printed straight - cyan, magenta, process yellow - thinning the inks to match a Florescent color pallet of cmyk.
I blew up (no pun intended) a very small 1.5" x 2" image from a Deptment of Energy document from the 1960's.
The films were insanely expensive ($600) but the end result was worth it.
