I might belong to the last generation who grew up using these touch tone style handset telephones (aka, the Trimline). I see them pop up regularly at thrift stores, yard sales, and on eBay. They're commonly found stored away in garages, attics, and closets, disconnected and forgotten. But check out this DIY reuse project, which transforms them into a useful decorative accessory with just a little spray paint and drill worthy of display today...
Erin and Stefanie of vintage boutique, Oh So Lovely, recently produced this project for A Beautiful Mess, illustrating how to convert these communication relics of the analog age into vintage-style decorative bookends. You'll need a heavy duty drill and an appropriately rated drill bit to make holes through thin metal strips and into each handset bottom before attaching one to another into a bookend base.
