This is a 1990 the Wall Harley jacket bought at auction long time ago. I just bought it as a jacket to wear but upon receiving it a friend saw that it was signed by Roger Waters and 1 0r 2 others yet to be i.d. You can barely see it. Are the signaturees real, and is their a accepted way to enhance their visibility? And how to protect them when wearing the jacket? Or is that possible?
