Happy Birthday coffee mug, Vintage Sandra Boynton

Vintage Sandra Boynton Happy Birthday coffee mug. Features numerous cats from smallest to largest encircling the mug. Each one is holding a colorful balloon with the text "Happy" on it and what I love is as you look at the progression of cats, they go from expressionless to a toothy smile. It will be sure to put a smile on any one's face! Makes a nice gift to give from a family, group of co-workers or group of friends. Made in Japan and in excellent shape. Please zoom in on photos for detail. If
