In the early to mid 1970's, the phone making company American Telecommunications Corporation (ATC) had a line of novelty phones called the Deco-Tel line. One of the more popular phones of this line was the Candlestick phone.
The phone sometimes used Western Electric parts, sometimes Automatic Electric parts depending on who was selling it.
Even though it looks classic, it does have modern componentry so that the sound is good and dialing is smooth.
