Well, like I said I went to Zazzle .com, you upload the image you want and they have it printed and shipped to you as a poster with several different quality paper and finish options. It arrives within a few days. the hardest part was gluing it to the foam core and then cutting the foam core. The one I printed starts was 34.95 and measures 52.5" x 26.5". I;'m happy with Zazzle but I’m sure there are other print sites out there you could use. I’m thinking of revising the map and printing it in the next size up, 39"x78 even thought it’ll probably cost me $150 or so. I love the idea you had of the gdp. when I did my map I used the militarys budgets but fudged it a little after trying to figure out the average spent per soldier in each alliance.
I’d like the cat more If it didn’t chew the map to pieces.
