Im fairly sure the year is just an estimate (guess), the company made this type of advertising stuff for many years, and still does...
Brown & Bigelow is a publishing company based in Saint Paul, Minnesota that produces advertising specialties, or promotional products, such as clocks, pens, cocktail spoons with corkscrew and cap-lifter, and advertising calendars. The company was founded in 1896.
In the late 1940s, it was one of the biggest calendar printers in the world.
(from Wiki page)
the company still exists today

baseball collectors usually know the playing cards but they made alot of other things with the same painted baseball images, like blank cards that had advertising printed on back (or team schedules like yours), very similar to the 19th Century tradecards. They also made large calenders, address books, and a few other items with that same Ruth image. there are quite a few different types of images, from boy scouts to vargas girls, etc, most all from that Era are the same style of paintings (many well know artists)
your card would be scarce and would have a slight premium over a common playing card but wouldnt have great value IMO. the playing cards are very common and still often found in unopened decks.
here is an auction that shows a calendar and a Ruth Address Book
