Over the years, I've hung a large poster of my sports car in my garage (1st Gen RX-7, 3rd Gen RX-7, 996C2, 993TT, 996GT3). A few years ago, when I got my 997GTS, I looked for one, but only found a poster of a white coupe and a white cab, no black.

First, anyone know if a poster was made with a black 997GTS?

Secondly, and more appropriate for this audience, if I wanted to have a 24"x36" poster made from my own photo, where would I go? I have a 20 megapixel DSLR. Shoot RAW?
