Stumbled across this tonight-
There is an extended scene from Measure of a man that shows Data's Diploma packed into his suitcase-
As per Ex-Astris.com-
"Data's Starfleet Academy diploma can be seen up close in this shot. His name is given as "NFN / NMI Data". NFN stands for "no first name", NMI for "no middle initial"."
Can somebody pull a better screencap of this shot?
