Refrigerator redux

In addition to the powerful magnet that came out of a broken chargeable flashlight (upper left), our refrigerator is festooned with magnets handed out by local businesses. The little blue half-garafa (propane tank) I actually found in the street but thought pretty cool. Outside of paper ads, held in place by other merchants’ magnets, there is only one non-magnet on here. Can you guess?

The guys who fix refrigerators. They put on a sticker.
