NeXT Developer , Display postscript programming treasure Steve Jobs NeXT logo black Turtleneck DNA ?

Hello NeXT community: I thought you all would get a kick out of seeing this massive hoard of NeXT and display postscript documentation that just came in today.
Sungwon I have definitive proof in one of the letters that there was indeed a set of manuals for version 2.1 and now I know the part numbers !
I think I have this set for you.
For everyone else enjoy there’s some really neat shirts and one of them may have been from Steve Jobs himself.
I wondered if there’s a way to check for Jobs DNA lol .
I’m serious how many people out there would wear a black turtleneck with the NeXT logo. They kept it 30+ years as well , fun addition to my home collection display .
You all have a good day.
Best regards, Rob Blessin.
