Richard,
That is my 1928 stub on eBay.  Its priced high.  I've sold 3 of these stubs over the years from $1000 to $1700.  That one on eBay is the best condition of all of them.  
Obviously a full ticket does exist in order to make the fake one, but I've never seen it or felt the urge to take a chance.  
Here are pictures of the other ones I've been offered over the years.  Their grandfather usually had them "since the game".  I always ask for a photo and then add it to the "fake collection" folder when it comes in.
