Well for only a few parts, the Apollo spacecraft, the CSM and Stabilizer Fins, plus engine bells.

Why would I use this $4.65 per 11"x14" size sheet?

Check out the photo for this answer. Yes, it is Paper and ink. You can see standard cardstock version in the background. There is no gloss coating on the paper, it is just paper and ink-same color as background version-this photo paper really is some cool stuff.
