we were cleaning out an attic and found a bunch of old pepsi blueprints of the colorado springs plant. we posted one on ebay if your interested in bidding, i have never seen another one of these anywhere in a collection!!!! it is folded and has some aging on the folds but in spectacular shape for its age. http://www.ebay.com/itm/Rare-Pepsi-Collectible-Vintage-Blueprint-From-Colorado-Plant-1975-/122034191169?hash=item1c69cdfb41:g:aVwAAOSw-KFXeHJs
