Wednesday Daily Wrangle: Neatorama's got Carpenters footage, find the Barbie patent

Neatorama kindly shed some light on our lost pop culture initiative and noted The Carpenters doc referenced is available online. The film infamously used Barbie dolls in place of characters and received an ominous letter from Mattel referencing the toys’ patent. For a unique wrangle, can you find the original Barbie patent online? Happy Wrangling.
