Several years ago I ran across a Majestic Charlie McCarthy radio at an antique store. It was a midget radio with a plastic, or more likely bakelite moulded image of Charlie. They also did models featuring the Lone Ranger and Rudolph. Today each of those radios could bring up to $500- $1,000 at auction, maybe more depending on condition.
Recently I was thinking it's a shame The Shadow never got his own radio, so I decided to see if I could make one out of paper. Personally I think it came out pretty well. I've provided a link to the PDF and YouTube instructions so you can make your own. Each paper radio is designed to work with your smartphone and includes a cradle along with a QR code to give you quick access to an online library of Shadow episodes.
Thanks, and I hope you enjoy.
