Telephone Answering Machine

Description (Brief)
Telephone answering machines in the mid-twentieth century used a variety of recording media, some standard, some special. This TT Systems TeleTender IV used both. The incoming message was recorded on a standard tape cassette inserted into the top of the machine in the same manner as a portable cassette player. The outgoing message, however, was recorded on a small cartridge inserted into a slot on the side of the machine. Less than half the size of an 8-track cartridge, the cartridge received with this object is labeled, “Sunday - Summer.”
