Mystery Diner Mug With Flower And County or City Outline

This is a really cool diner mug that I purchased in Portland. I thought it was a Rose (Portland being the City or Roses) and an outline of the city. But it's not Portland and I'm not sure it's a rose... but maybe someone out there knows what it is and has been looking for one?!?! Regardless, it's a cool classic diner mug and it's in excellent condition and ready for a new forever home! 😊
