// Two big golden Christmas bells hanging side by side, slightly tilted toward each other, joined at the top by a red bow with holly leaves and red berries, hanging from a short dark green post. Each bell has a dark inside and a round clapper at the bottom.

// A green hanger and the bow stay still while the two bells swing.
