One of my coworkers pulled this out and stumped all of us under the age of 40. So I am curious! Do you know what this is?? (Don’t cheat. But I reveal what it is under the pictures. )

What are your guesses?!?!

If you’re not sure yet… Here’s a clue. I zoomed in on one of the pictures. Take a closer look…

Okay here’s what it is…

Phonograph Cylinder! They are the earliest commercial medium for recording and reproducing sound. Simply put – they are records! They were invented in 1877 and were most popular between 1896-1915. Pretty crazy to see how much music has changed over the years! Who knows, maybe these will make a comeback like vinyl has!
