Someone is selling LEGO-PDF instructions on eBay. I bought this one:

http://www.ebay.co.uk/itm/10002-RAILROAD-CLUB-CAR-TRAIN-INSTRUCTIONS-ONLY-RARE-LEGO-MANUAL-/140925003195?

and except the size of the file it contains pictures with the same errors as instruction I downloaded from worldbricks. Is it legal?
