I wish I had something to offer besides just remarking that this is nice research...and that I really enjoy these cards!
Of course they use a bunch of the same poses as York Caramels , Yuengling and Harrington and a few other B & W sets of that time period, so that is some of the charm to me.
I have scans on my laptop, none accessible on this IPad but I may attach some later.
These are not very easy to find, so I have never tried for the set...even though I have a notorious sweet tooth
