The Kitchen set of  the “I Love Lucy” New York apartment featured a distinctive square breadbox with matching canister set made by Nesco.

The door of the breadbox  was a pull down style with a handle at the top.  By the third season, the bread box had to be turned on its side to keep the door from falling open, which happened on screen in one episode when Ricky walked into the kitchen,

Lucy quickly went over and closed it while speaking her dialog.  After that the breadbox was usually seen on its side -probably to prevent the door from flipping open whenever the actors moved around the set – until the Ricardo’s moved to their new Connecticut home after which it was no longer used.
