Here is a miniature “book” found in the library [2 by 3 inches] – a promotion/prospectus for potential advertisers, giving some sense of what this new magazine, Sports Illustrated, would be like.
What it looks like it will be like is a lot of saturated color photographs, which makes this little treasure like an artist’s book [or zine?] more than advertising ephemera.
Nerdy library trivia to give you some context: Sports Illustrated started with August 16, 1954 and [after issuing about 53 issues per year] it is still plugging along. According to Worldcat, the world’s largest largest cooperative catalog, 5,773 libraries carry it. In the 1970’s, the grade-school library in Central New York my mother was librarian of requested that she not have the swimsuit issue available on the open shelves.

I’m pretty sure you can still have the Swimsuit issue be withheld from delivery if you are opposed to it.
Not I. My mother and I share a kind of shy Librarian First Amendment appreciation, which wonders at the level playing field given to swimsuits and Renaissance art!
