Trapper Keeper

Popular with students in the United States and parts of Latin America from the 1970s to the 1990s, it featured sliding plastic rings (instead of standard snap-closed metal binder rings), folders, and pockets to keep schoolwork and papers, and a wrap-around flap with a Velcro closure (originally a metal snap closure).

In preparation for test-marketing, Crutchfield wrote a commercial and flew from Dayton, Ohio (the headquarters of Mead) to New York City.

To everyone's surprise, the product inventory sold out, and the 1500 feedback cards returned revealed that adults as well as teens were buying Trapper Keepers, for non-school uses.

[1] Three years after the Trapper Keeper was released, the design was tweaked to include a Velcro strap instead of the initial metal snap.

"[1] From 1996 to 1999, Mead released a collection of notebooks and folders known as "FuturoCity", featuring futuristic city and landscape designs.
