Throughout the debates of EU/Legends vs Nu Disney Canon there is an entire age of SW lore that is all but forgotten. I'm talking of the Pre Zahn, Pre WEG stuff that was actually released in the OT time window, well before any canon policy was in place or argued over.
Stuff like the OT Novelizations, Radio Dramas, Lando and Han books, Marvel Comics (over 100 issues! Plus the UK stuff) two seperate daily comic strips, Splinter of the Minds Eye, the holiday special and all the other TV ventures like Droids, Ewoks and the two Ewok movies. Not to mention ET and Raiders had Easter eggs linking them to the OT. All of this now exists in the forgotten mists of time because of the second and even third generation of fans being totally ignorant of it or immediately dismissing it as juvenile when first introduced to it.
WHAT A MISSED OPPORTUNITY!
This is among the earliest SW to ever exist! This should be the first stopping off point on any SW extra curricular studies. Instead it is all ignored and forgotten.
Sure much of it contradicts the OT or later movies, and even contradicts other sources from the 76-86 era. But there is still much to mine for rich idea, plots and characters.
Let's not forget the first golden age of SW.
