It may be in card form but it might have been given out as a bookmark. In any case I've never seen that before. It might be British in origin because the volumes don't match up to what's listed in Wikipedia unless that list is of the British version of the series.
It might be as old as from around 1888 since that's where the list ends. I can try asking some book collectors about this.

Is it in Chris Benjamin''s non sport book? I have looked in the British Trade book and there is no listing for Put am so I think that it is a US issue. Also note that Putnam reissued some of the books with different titles and to me the booklist may reflect that.

I received a few replies. One collector said this:
"In addition to what has already been stated- the type face and principles bring style is period correct- and the listed price per volume of 1.50 is a big clue to age- linking these to the late 1940s early 50s printing. You are correct that these are advertising “handouts”. These cards were used by door to door salesman, a common practice at the time. The block print is a monochrome of the 1887 edition trichrome cover."
