While working at Shure in 2014 I was asked to consider how the company could celebrate the 75th anniversary of the first unidyne microphone (the one Elvis used to rock). These paper microphone kits allowed audio fans around the world to make their own and share it with our social media platforms. It was fun to see folks get the glue and scissors together to all craft something purely for the love of the tool.
If you would like to build one yourself, here's the archived link on Shure's site: https://service.shure.com/s/article/unidyne-model-55-microphones-make-your-own-paper-models?language=en_US
