Vintage Rival Crock-Pot Slow Cooker with Removable Server

This is a vintage Rival brand Crock-Pot slow cooker, likely dating from the mid-to-late 1970s or early 1980s. The unit features a classic avocado green exterior finish with a mid-century illustrative border depicting various vegetables such as mushrooms and carrots. It is identified by the blue 'RIVAL CROCK-POT' logo on the front, along with the text 'REMOVABLE SERVER,' indicating that the ceramic insert is detachable from the heating base. The control interface consists of an oval-shaped plastic panel with a black rotary dial indicating 'OFF,' 'LOW,' and 'HIGH' temperature settings. Physically, the item appears to be in used but preserved condition; the metallic or painted exterior shows some minor surface scuffing and light patina consistent with age. There are no major dents visible in this view, and the graphics remain legible. The construction is characterized by a heavy-gauge metal outer housing supported by small black plastic feet. The interior stoneware is visible and appears to be a light cream or off-white color. These units were renowned for their durability and heavy-duty heating elements, representing a significant era in domestic culinary technology.
