All of the “blueprints” I showed previously were based on the same basic color palette. But the actual vintage blueprints I’ve seen vary wildly Most are blueline or brownline… i.e. the lines are blue or brown on a white background. These have of course been replaced with black lines on white paper in the digital age. These, though, while they seem to form the bulk of such diagrams, are visually BLAAAAHHHhhhhh.
I’ve seen a number of German WWII-era blueprints, and the vast majority of the ones I can recall have all been brownline, not blue line, and not (sadly) whitelines on blue backgrounds. Still, age has turned the white paper slightly “tan,” which is more appealing than plain white. So, I went ahead and created a “vintage brownline” of the V-2 (A-4) rocket cutaway:
Printed full size, it would be 16.5 inches wide by 56 inches long; it would be priced something like $45. A reduced-size version 12 inches wide by 41 inches long would be something like $25. Anyone interested?
