New York Knicks Game Ball Patrick Ewing Herb Williams Rolando Blackman and more

Description

I know this ball is authentic it was won by my father who worked for a major automobile company while on a company event where they attended the game. I also don't do any trade in sports memorabilia and I
am not a collector nor was my dad. I will help if I can in any  way  to authenticate this ball.
That being said a
new offical leather game ball by itself costs 9.99 and the fact this is a official game ball should help reinforce authenticity.
I am willing to take pictures or answer any specific questions if someone needs more information.  I believe it is from 1993-1994 from the signatures which are listed below.  I did my best to figure out who is who luckily some put there jersey numbers.  There appears to be 12 signatures on the ball but I can only identify 9 of the names/jersey numbers with any certainty.  I'm sure if you are a fan you may be able to identify the other 3. There are a few household names there so I have put a very reasonable price of 5.  Patrick Ewing signature alone can go for double or triple that from my research.
