Buyer Beware....
Not that anyone here would likely pony up the crazy asking price for this, but be warned that this is almost surely a reproduction pennant, and NOT original...

The spine and stitching are all wrong for this pennant and it should be oversized (not full sized). Note how the seller's measurements include the tassels. Likely made by Mitchell & Ness, and heavily/artificially aged and weathered to look old.
Stay away!
