I did finally pick up the first Marvel Dark horse omnibus volume and plan to jump in straightaway. I almost read the new recolored versions from the library but couldn’t stand the look of them.
I’m curious, would that be one of these two?;

The latter was my first introduction to Marvel SW, though it took me a several years before I even realized it was made by Marvel as they erased the Marvel logos from the covers and replaced all the “Stan Lee presents…” with a generic “LucasFilm presents…” I guess I technically could have googled it, but 11 year old me in 2003 didn’t know how (or that google existed). The funny thing is that the art always gave me a Marvel-vibe and I was quite surprised when I a few years later come across a picture online of one of the covers (can’t remember which) with a spider-man head in the bar-code box.
Either way I’d recommend picking up the second volume as both editions cut off right in the middle of one of the best runs (the best IMO) of the classic Marvel SW series. Though the 2010 omnibus cuts off at a more appropriate point between story arcs. The first post ANH story is IMO a bit too wacky and cartoony, but once Archie Goodwin started writing in #11 it gets really good.
