This image is of the original kitchen built at the founding of the Mission. The metal tools were used to remove pots from the oven and the fires, as the metal pots would be dangerously hot when used for cooking and often had no handles.
The description states:
MISSION SAN JUAN BAUTISTA
Founded 1797 – San Juan Bautista, California
The Mission kitchen is the original, containing ancient cooking utensils, fire irons and the original bake oven. The walls feature built-in cupboards. Once completely plastered, now brick and adobe construction is in evidence.
–The presence of a ZIP code on the card indicates it is likely from the 1960s.
