1987 Heather Harms birthday mug by Applause vintage 80s ceramic coffee cup

Vintage 1987 Heather Harms birthday mug by Applause. It’s a white ceramic coffee mug featuring a woman sitting in a big comfy chair and says “Don’t be sad you’re not as young as you used to be… Be happy ‘cause you’re not as old as you’re going to be…” Happy Birthday is written on the inside rim of the mug. Good condition with one tiny chip near the handle (see closeup). Measurements in photos.
