A radiogram is a piece of furniture that has a radio and a record player built into it. It's like a big wooden box that you can put in your living room or bedroom. When you turn it on, you can listen to music or news on the radio, or you can put a record on the record player and listen to your favorite songs.
It's kind of like a modern-day stereo system, but back in the day, people didn't have separate components for the radio and the record player. Instead, they had a radiogram, which combined both into one piece of furniture.
Overall, radiograms were very popular in the 1950s and 1960s, and lots of people used them as a way to entertain themselves and their families. They're not as common these days, but they're still a cool vintage item that people like to collect and display in their homes.
