Oh the Bells! Bells! This 'service needed' bell is hardly seen any more, (I used a photo reference as I'm out of town again!). We do have one, though, at the cashier's window at the college. Remember when they sat on every grocer's counter?
I'm thinking also of other bells: church bells ringing out festivals, hours, ceremonies, mass, life events; door bells, jingle bells, the bells on the ice cream truck; the hand bells making music for the chorus, and the novel "For Whom the Bell Tolls."
