HI!
so details about the musical windup knick knack

it plays winter wonderland
it is circular in shape, about 5-6 in across and about 5-6 inches high
on the circular pedestal are four rabbits, made of hard foam and
covered in felt
they are positioned around the outside of the circle and in between
each one is a polka dot mushroom
it was orginally purchased in Michigan between 1969 and 1979

looks like the sort of thing you would buy at the five and dime or at
a crafts fair
does not seem to be unique (though my frustrated searches say
otherwise)
