Stadium blueprints.
 

How can you tell if stadium blueprints are original and not reprints. Specially when looking at ones online and not able to inspect it in hand. Also the one I'm looking at. There seems to have been copied made before of it but their white. So we're there multiple sets of the same blueprint???

There are so many subcontractors involved in building something as big as a stadium that there will be many, many sets of blueprints.

There are lots of blue prints for each job. There is always the master set in the head office on site. Another at the General contractors main office. Then every sub contractor has at least one set. Most of the sub contractors blueprints are only of the portion of the building they are doing the work for. For a project the size of a stadium there are easily 200-300 blueprints out there and that is not counting the 100's if not 1000's of partial blue prints sent out for bids and off site contractors.

The blue print used on site are all white. Hope this helps.

Are you talking older blueprints that are actually blue, or modern blueprints that are actually white? Modern "blueprints" are essentially like anything else you would print out on your computer at will, just on a larger plotter (printer) than most folks have at home. Older blueprints are, by their nature, also all reproductions of the original hand-drawn plans, but are more like oversized versions of the mimeograph tests and worksheets we used to get school. I imagine even these could be scanned today and reprinted in color (there goes all the blue ink) to produce something that would be indistinguishable in an internet listing until you had out hand.

Sorry should have put that it's supposedly a 1920s Yankee stadium blueprint. i'm guessing it's a reprint even though the seller says it's original because it looks exactly like this print.

As bnorth said, just because it's identical doesn't mean it's a reprint....there would have been many, many sets of original blueprints.

1920's is way different than modern. I have worked in construction since 1989 and have seen 100's of new white prints of every size imaginable. The only old original blue prints I have seen was on very thin paper and left blue on your hands when looking through them.

This one is a reprint. I'm sure the one you're looking at is a reprint, too.

Blueprint question
 

That ebay listing is most likely a copy as most of the Yankees are. I've handled 1,000's of blueprints over the years from League Park up to the newer modern stadiums. Their are 1,000's of blueprint pages per stadium due to the size of the structure and they do have one master set as well as different versions from the design phase up to the final drafts.
