Pair of vintage noisemakers in the clacker / clapper style with a small square of metal that rat a tats back and forth.  
Both in shape of cats.  Measure 8" long by 5" wide (across ears).

One is colorful and bright with images of bells, horns, clowns, and firecrackers - perfect for a birthday.
The second has a New Years theme with clocks showing nearly midnight, bells and champagne glasses.

Not marked.
