BF Goodrich introduced the Zipper Boot in 1923. It was one of the earliest successful uses of the Hookless Slide Fastener. The fastener became so inseparable from the boot in these early years that the boot’s name, the Zipper came to be the generic term for what had previously been called the Hookless slide fastener. This ashtray depicts the early version of the boot, from about 1924, which features the no-hole version of the Hookless fastener.
