Interesting that in the 21st century, a black-and-white product would seem "new." If they are less-common images, they'll be cool. If they are mainly just B&W versions of well-known shots, not so much.
I found a couple of cheap online lots (I now have about 80 of these; the set has 140 in its base); the photos are of angles I hadn't seen before of ANH. I doubt I'll fill in the missing cards (as there's almost half left), but they are nicer than I expected due to these less-common images.
After waiting and searching (plus buying some loose card lots; apparently one where I had every card already), I got a complete 140-card set for a bit over $20. Those shots I hadn't ever seen before are really great! Worth looking into.
