'strip' cards. I think some of the ones pictured come from a set of about 200 cards. Likely issued circa WWI or so. Don't know much about the ones with something on the back. Most of the strip cards I have are blankbacked. Maybe someone else can chime in. The baseball versions of the strip cards are pretty well documented but the non-sports ones are kind of Wild West stuff still as far as I know. Not much out there on them. Looking at my American Card Catalog, I think some of yours are from the W545 series. Numbered 1-200..........
See the picture attached for a page from the ACC. You can pick up an ACC from ebay for $15-$20 in a reprinted 1960 copy. They are want for detail though. Just basic information.
