Portable and darn cute.  Irresistible. Measures 12" x 8" x 7". From a great marque.

The company was co-founded by Ralph Matthews and Karl Hassel in Chicago, Illinois, as Chicago Radio Labs in 1918 as a small producer of amateur radio equipment. The name "Zenith" came from ZN'th, a contraction of its founders' ham radio call sign, 9ZN. They were joined in 1921 by Eugene F. McDonald, and Zenith Radio Company was formally incorporated in 1923.

The fledgling company soon became known for its high-quality radios and electronic innovations. Zenith introduced the first portable radio in 1924, the first mass-produced AC radio in 1926, and push-button tuning in 1927. It added automobile radios in the 1930s with its Model 460, promoting the fact that it needed no separate generator or battery, selling at US$59.95. The first Zenith television set appeared in 1939, with its first commercial sets sold to the public in 1948. The company is credited with having invented such things as the wireless remote control and FM multiplex stereo.
