That numbering in the lower-right corner (look close for No. 10-11-05) means this is #5 in baseball's film series, just one sport under Action Cartridge's umbrella of cartridges for golf, basketball, football, and hockey (full baseball checklist).
Each cartridge includes a Coaching Guide booklet with tips about the skill shown in the film, like "turning the double play" or "bunting." (I assume the film clip's just a video highlight without additional commentary, hence inclusion of the Guide.)

Some films come shrink-wrapped, others with cardboard backing, and still others in a pack with the camera and other films.
Action Cartridge produced several cameras during this product's life, including one with a backlight that required AA batteries. All used the hand-crank and viewing lens, but several had a foot that allowed watching from a table top or in-hand (as shown on the box).
Controlling film playback (forward, backward, slow-motion) with the hand crank felt pretty cool, I bet. The rarest model, supposedly issued only with hockey films, has a pistol-grip handle and image focusing wheel (the small black dial).
Value: This sealed #5 cartridge sold on eBay for $28 in November 2013. Films with superstars like Pete Rose, Reggie Jackson, or Tom Seaver might cost $50+ in high-grade. Unnumbered player "cards" (trimmed box panels) would be easier to store in pages, but sell for significantly less than intact packages. (The films aren't well-known or popular within the hobby, so sellers might wait quite a while before finding a buyer.)
Fakes / reprints: It'd be tough to fake a product this intricate and seems too obscure to make reprinting box panels worthwhile.
One thing I can't find is any digitized versions of their films. Until those surface, enjoy this Super-8 home movie of the Cubs and Mets (Seaver's win on July 22, 1971), which includes Don Kessinger--IN ACTION!
