I managed to snag an image of the instruction card issued with the larger version of the set recently and it's pretty neat:
I like how you can make out the bare outlines of the World Leaders subset in panel 3. It's a lot more detailed than most instructional drawings from Topps over the years. The card also shows signs of high speed "ribbon cutting' where strips of uncut cards were cut at high speed, resulting in a slight curl that's just off kilter.
The back is plain Jane man:
I still need an example of the blue developing paper and although I don't collect wrappers per se, I do collect the penny wrappers from these tiny little issues.
I bought my panel from Larry Serota, known to many in the hobby as a collector of many hard-to-find cards. Larry also had a number of auctions going on eBay with small and large groupings from the set. Here are some undeveloped and uncut panels of the large sized cards, as inserted in the nickel packs, showing how panels of four plus three came packaged, although I have seen some that may be only "twos" (hard to tell this long after the fact):
It's one of those sets where the backs look nicer than the fronts!
As previously noted on the blog, the small cards do not show signs of perforations or dotted lines as they were inserted as singles in the penny gum tab packs.
As I stated above, I'll be focusing more on the 60's and 70's going forward but will still, of course, post anything worthwhile from the earlier decades of Topps as items come to my attention.
