This is an amazing vintage Duncan & Miller Canterbury Rose Bowl. The bowl changes color from a light blue to a purple color based on the lighting in the room or area. The bowl measures approx. 5 1/2" across at the widest part. The bowl is in good condition with a couple small flea bite nicks on the bottom edge, Please see the pictures for better details. I tried to capture the changing color but the pictures do not do this bowl justice.
