G.I.Joe Phones

Pictured above is a set of G.I.Joe Phones. Released by Durham Industries, Inc (under license), they are dated 1982.

They aren't "regular" phones, but are more of a toy intercome system. When a number is pressed on one phone, it buzzes the other phone and the other phone's red light comes on. If both parties pick up the receiver they can talk over an intercom like system.
